I think this is the best "All-in-One" Random Tables product you can get for Sci-Fi settings. One thing I'm missing here is a table for events on planet's surface. There is a Planet Event table, that somewhat covers it, but a lot of outcomes are planet-defining (like toxic atmosphere, ocean planet with some horrific creatures beneath the surface etc.), which is a good thing if you look for a adventure ideas, but not that great if you want to drop a random event on a planet that you've created.

Let's be honest. This ruleset might not be for every OSR fan out there, certainly not for the most hardcore OSR fans. But what it does best is that it brings OSR-style adventures into 5e games. By all means it is still 5e and if you didn't liked 5e base mechanics (like combat system, proficiencies, backgrounds and inflated HPs) you might not quite like this one as well, even though a lot has changed. Nevertheless it is a great rule system if you, like me, play with people that are not accustomed to OSR games usually because of high leathality, very few character options and specific style of play. This game builds the bridge between 5e and OSR. It throws out the window all the unnecessary, complicated stuff, but leaves enough character options so that most people will be satisfied. It doesn't ends here, as every class is in many ways is similar but different to their 5e counter-parts so that all the 5e players should feel that they came across something new, but familiar at the same time - and it is all made in the spirit of OSR games.

With many of it rule variants it is also a highly modular game, allowing DM to change up many things to their liking, making it resemble OSR games even more. There are some excellent rules, like even HARSHIER healing, Grevious Wounds, lasting Critical Hits and many more that will make your game even more deadly, while still giving your players some space to breathe. It also does great job at teaching what OSR-style adventures are like and how to DM them, so it is a great choice if you want to DM OSR-style game but you are new to this whole "new" concept. I don't think there is a better game that explains to modern players what OSR is like while at the same time making the transision painless (there are probably better OSR games, but most of them are very rough around the edges and not very appealing to more modern audience). I think that both hardcore 5e and OSR players will find here something to their liking.

Is it perfect system? No - there's no such a thing. Being a good DM is an art of compromises as you need to choose between what you like and what your players enjoy, which doesn't always align. For me ItU was the right choice as it allowed me to continue nursing my love of OSR-style campaigns, while at the same time having modern rule system with enough options so that my players can enjoy their characters.

I believe that for a long time to come this will be my main rules system, especially that it created a great foundation for DMs to build upon. Also, me and my players can't wait for the Companion book, which is possibly coming out this year. Keep up the good job, Anders! You've made a lot of people happy with your work :)

Being very expierenced GM that I am, I hate being dictated by the rules on how should I run my games, which is the reason I don't really buy into modern RPG design. BRP family is one of a kind; a tabletop-rules systems that is what RPGs were supposed to be in my eyes - a toolbox of rules and statistics that paves the way to our imaginations and helps bringing balance to the adventures and worlds that we create. No more, no less. This is what M-SPACE truely is. It is a complete system, one that does not require you to add or substract anything from in order to run your space-faring game. However it will also not break if you decide to do things your own way, which is not a common thing in a modern era of RPGs, that resemble board games with rules that are there to limit your potential and your imagination, so that every game session plays at the same, rather average level. There are no rules that will dictate how your players should roleplay their characters or how you should run your games. It's a sandbox of a rules system, which means that it has all the necessary rules to run a game in a SCI-FI universe - from PC's skills and attributes to equipment, combat rules, space-faring, alien creation, force (psionic) users and world building.

You can run anything SCI-FI related with M-SPACE and with very little changes. You can easily create Jedi Knight with the rules written here, Space Marine, galactic politican or Stormtrooper. As it is with all the BRP-related games; M-SPACE is very universal in a sense that every character, monster or robot is made of characteristics, attributes and skills. They all follow the same rules, making them more believable and easy to create. I could write much more on why D100 is the best system ever, but it has been said already so many times on the internet, that I don't see a point of repeating what other great minds have already said ;)

I cannot recommend more this game. Buy it! It's the best SCI-FI system that I know, that's for sure.

Great PDF. They've even added combat manuvers and mounted combat! All the rules you need in combat are here!

The best WFRP supplement imo. I love it for it's dark fantasy atmosphere.

Probably the best fantasy RPG out there. If you looking for something different from D&D get it! But remember; this is grim world where death is always near.
