In Old School Computer Game (OSCG) you create a party of adventurers and explore a sandbox world, completing quests and accumulating treasure and experience as you go. In OSCG, I have attempted to re-create the fun of my favorite computer role-playing games from the late 1980s and early 1990s. The game mechanics are based on the excellent retro-clone Dark Dungeons, the interface is a mash-up of early PC and console games, amd minimalist art conveys the game while leaving the details to your imagination.

Features
- 13 classes: bards, clerics, druids, fighters, magic-users, monks, paladins, psionicists, rangers, thieves, dwarves, elves and halflings
- 13 kits and 7 spell school specializations to choose from (there are 99 possible class/kit/school combinations)
- 199 spells for magic-users, 56 spells for clerics, 79 spells for druids, and 34 powers for psionicists
- 450 opponents to encounter and defeat (and another 323 subtle variants)
- 2601 magical items to find and use (including 4 end-game reward artifacts)
- a large, randomly-generated world map to explore, featuring hundreds of dungeons, ruins, castles, towers and pyramids
- over 250 quests to complete (a mix of randomly-generated and hand-crafted content)

The game is written in Java, and will run on Windows and Linux computers. I have included a Windows installer; security software may flag this as from an unknown publisher, as the installer is generated using a simple tool. To run the game on Linux, you will have to install the Java runtime yourself, and then run the JAR file.

The game contains content licensed under the Open Game License version 1.0a. If you unpack the JAR file (you can use 7-Zip or any other ZIP file manager), you will find a directory called "opencontent". This directory holds the "OGLv1.0a.rtf" file (which details the license), and all of the game's open content. You are free to change or use the content in this directory. You can even hack the game by modifying these files - the spells, monsters, magic items and character classes are all defined in spreadsheets in this directory.

Developing OSCG has been my hobby for over ten years. Your feedback, especially constructive criticism, is most welcome. Please use the comment section below to ask questions, suggest improvements and request new features.

Old School Computer Game Update 24: End Game

OSCG has long been an open-ended sandbox game. I have added an end game. Characters of 9th level or above can participate in a winner-takes all contest to conquor the Known World using armies and mass combat rules. The prize for the winner is an artifact, awarded by the lady of the lake. There are multiple artifacts to win, so replay is still in the cards. I am very excited to deliver this update - I have been working towards this point for over a decade!

As usual with upgrades, your existing saved games will not work with this new release - before you download and play this version, please load up any games with characters you want to keep and export them to disk in the manage party view.

Important
- Starting at level 9, you can now engage in a war for domination, and conquor the Known World.
- There is now an instructions panel, accessed by pressing F1. To leave it, click the "return" buttons at...See more

I'm sorry to hear that. If you prefer, install Java yourself (version 8 or newer), download the JAR file to any directory you like, and run it from there. The installer is meant to make life easier, but the old way still works just fine. (I wish I were better at customizing the installer, but there's only so many hours in a weekend ...)

have played your game a bit across a few years and have enjoyed it ; bought a number of years ago. I have a number of other PC games and have got into the habit of modding games to make them how I want them. Is it possible to maybe make a Higher resolution of the Monster pngs so that users can substitute their own favourite pictures to use and make the game more fun? I have tried this already and it does work OK but the 32by32 png size is limiting when I add my own pictures ,the medium sized monsters at 64by64 are cool though-could you maybe double the size (or more) for monster pngs to enable this feature I would like. I am sure other users could get some fun out of it as well. A game similar to your game on Steam called Low Magic Age allows users to do what I have suggested, and this is what prompted me to experiment modding your game, which is great vanilla by the way. Just an Idea.

Could anyone with firsthand experience with this game please tell me how faithfully this game recreates the experience of the of the "unlimited adventures" game that was released in '93 & the series of predecessor games that were initially released in golden color boxes? Does the game try to emulate the same first edition rules set mechanics? Are there any "quality of life" improvements to the game like the "Gold Box Companion" at gbc.zorbus.net provides to those aforementioned predecessor games?

Hi Tom. I'm the author. You may want feedback from someone else for objectivity's sake, but I'll try to answer your questions.

I loved playing the gold box games, and they inspired me to write this. However, the game is different in many ways. Some of the differences are:

My goal was to write a game that was the same kind of fun as the gold box games. I did not attempt to closely re-create them. For example, the SSI games had a 3D perspective, while I only use an overhead 2D view. There is no mystery in mapping, no need to write anything on paper - the game auto-maps as you explore.

I used the basic rules, as published in the free clone Dark Dungeons, and then modified them based on my preferences and extensive play testing. The game is similar to first edition rules, but not too close. For example, it features many classes and tweak those kits, but you cannot dual-class. (Kits are an idea I borrowed from second edition.) Another difference is saving throws - I...See more

Old School Computer Game Update 22: Another Coat Of Polish

Since the beginning of this game, I have had a gap that annoyed me - I had spells that had a single target (acid arrow) and area effect spells (sleep), but no code to support spells like magic missile and hold person where you can select multiple, individual targets. I have finally corrected this, and removed some silly spells to clean things up. For example, Hold Person can now target up to four people, but inflicts a save penalty if you target a single creature; this removed the need for Hold People, and so that spell is gone from the lists.

I have re-worked the randomized quests to (hopefully) make them more fun. Nothing major, just rearranging which monsters are paired together to make things less monotonous. (How often does one want to clear a crypt full of one kind of undead anyway?)

The game features a number of options (map labels, sound effects etc) that you can turn on or off. They used to each have...See more

Keep up the excellent work!!! I have a couple bug reports.

Bug report 1: I do not seem to be able to have my fighter specialise in a weapon after I levelled him up: I thought I could postpone the decision, but once he had enough XP for the next level, he could be levelled up, but the option to train in a specialised weapon was gone.

Bug report / unexpected behaviour 2: The spell Read Magic disappeared from my Elf's spell book after a couple uses. Or maybe I misremember how I used it in the first place? Picking the (C)ast spell option from being on the wilderness map does not show the Read Magic spell among the options, nor is it among the known spells on the Elf's spell list.

Both have happened after loading an old game in the new version of the app, though, so it might be my fault for not doing things as I should have.

I've been enjoying this fine game again after this latest update. After many hours of heroic adventuring, I've actually encountered a bug.

When the Kensai trains a weapon specialization, the weapon picked won't match the one chosen. I worked around this by updating the character file, but wanted to report it, too.

I am trying this on a 2009 MacBook (10.11.6 El Capitan), which I do understand you did not develop/test this for. The game looks FANTASTIC and truly a work of love... until combat starts.

Sadly, when combat starts, it all suddenly slows to a crawl, to the point of unplayability. One minute or more per event, e.g.
1) I clicking on a cursor key to pick the nearest target. One minute passes with nothing happening...
2) I hit enter to attack. Another minute passes with nothing happening...
3) The attack gets resolved. Another minute passes...
4) A goblin takes an action. Yet another minute or even two pass...

Looking at the activity monitor, it looks like the app uses about 1.5 GB of memory, is this expected? Wondering if this could be a Mac-specific memory leak.

Unfortunately I do not have a different laptop to test it on at the moment.

I am sorry to hear about this! Unfortunately I do not have any Apple products to try and re-create the problem with. This is not how the game works on Windows or Linux.

What version of Java is installed on your MacBook? Is it possible to upgrade to a newer one? Along with Oracle's official Java, there is the open-source OpenJDK version you can take a look it. OpenJDK works well on Windows and may be worth a shot on Apple as well.

Old School Computer Game Update 20: Continental

I have replaced the game world's archipelago with one large continent.

Can I ask if you intend to put in mouse-based controls in a future update? Something so that you click in whatever direction you intend to move, and so you can interact with inventory and so on. The game is great, but the key-based controls, at least for me, are tedious.

Andrew K February 09, 2020 3:34 pm UTC

Thanks for the question Darcy.

The mouse works in one way already - when you are in dungeon maps, you can move the cursor over a square you want to walk to, click, and your party will walk there.

I tried having complete mouse controls - inventory, stores, everything - but found it did not work well with the current interface, so I took it back out. One day I might try building a user interface for mice, that lets you drag and drop icons instead of work through menus, but that's a lot of work, and I may never get around to it. (I keep thinking about finishing the mass combat / run the world game, and that has to come first!)

I mostly noticed this one because the new setup for classes made my new party have Difficulties, but while my ex-Knight Errant and current Paladin dutifully objects to my Chaotic Thief or Elf (Archer) joining the party while she's in it, she has no objections to joining the party after they're already added. This is probably not the intended functionality.

That said, could we get a debug option to force wrong-alignment parties to work together, if you're going to fix this? Especially with possible changes to the class system that cause alignment conflicts that weren't an issue in the previous version.

Old School Computer Game Update 19: Let there be kits

I used to have 54 classes in the game, a very large number. Most were variations on a few base classes, and I found picking out the differences challenging ... and I am the one who wrote them! I have reduced the number of classes to 13, and variations now come as optional kits and spell school specializations added on during character creation. This increases the combinations available, while making the choices clearer. For example, the Kensai class is gone, but the Kensai kit is available to modify fighters, paladins and elves. There are now 13 classes, 8 kits and 8 spell schools to specialize in, for a total of 72 possible combinations.

Also, up to now, all classes were defined by formulas for aspects like experience level progression, spells per level and saving throws. I have moved this to tables in spreadsheets (found under the 'opencontent' directory for your use, should you want it), and changed the progressions to be...See more

I've really been enjoying OSCG, it's made me realize I was missing classic CRPGs quite badly. Last time I played I finished the last handmade quest, I'm currently debating whether or not I should level beyond my current (9-12) levels in random quests. I'd like it if there was some higher-level stuff to look forward to, like some sort of endgame goal.

If you're wielding a throwing weapon in your main hand and a non-throwing weapon in your off-hand, you can attack with both of them as throwing weapons, even though it will first say you're out of range for the second one.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
