Really fun setting and when you want something a bit more dark and punk rock for players when traveling interdimensionally.

Oh what a great book! I used this for a D&D setting when players traveled across the planes. They loved it.

You walk into an empty room... ugh how boring! Now your GM can spice things up on the fly! Some great fun ideas in this book for sure.

This is a good tool for any GM who is looking for a bit of inspiration from time to time.

These are great! I use them in Roll20.They work really well.

Really enjoyable AD&D style adventure. They do a great job of continuing the tradition of old school modules.

The Advanced Adventure series is really great! Perfect addition for any AD&D group.

Really well done adventure for 1st edition AD&D. Good job!

I think it is really smart to release a free quickstart guide. I feel this guide could do a better job of hand holding new players through combat. It is not very intuitive. But the design and layout is great.

This is a great book. I love the layout and the design. They did a great job of capturing the essence of Star Trek. My only complaint is that if you are new to this game system... the rules are not very intuitive. Particularly with combat. I have read and reread over and over again trying to understand "how do I attack, what do I roll". Its such a basic thing that should be easy to find... but it isnt. Or at least it isnt explained very well. The beginning adventure could do a better job of "hand holding" in that regard.

The theme is great. The artwork is amazing. I really like the encounter deck. Which is really smart because they can release new encounter decks over time to expand the game. Same with the map, I love that idea. BUT I despise there only being 4 levels of expertise/competency and I really don't like it being tied to a die type (d6/d8/d10/d12). If feels like an arbitrary design decision that works for a "one off" game. But if you want the option for a long term campaign with actual character development... 4 levels doesnt get you very far. Unfortunately, I don't see how that decision can even be fixed with a supplemental book either. Using percentile dice for skills would have been better design decision for long term play. Or even a d6 mechanic that increases the number of dice rolled based on how skilled the person is (2d6, 3d6, 4d6....10d6, etc). So the game works fine for one off games... or really short campaigns. But if your crew is travelling from Poland to the US? Forget about it. They will be rolling all d12's for everything before you even cross the Atlantic. Bummer.

Labels under the pictures and/or descriptive file names would be extremely helpful in determining when to use this art in the game.

Call of Cthulhu is and has always been a fantastic RPG. The newest 7th edition is a nearly perfect RPG. I could not give this 5 stars for two reasons. There are two updates to the rules that I absolutely abhor and I wish they had not done in 7e.

Bonus/Penalty Dice: This is clearly a D&D5e ripoff of the advantage/disadvantage system. Chaosium's implementation is overly convoluted. "Roll percentile dice then reroll only the 10's die, choosing higher/lower 10's". Ridiculous. Why not just reroll the percentile dice? Or, better yet, lets not even use this dumb rule at all. If an investigator deserves an advantage or disadvantage merely award a +/- 10% to the roll. I absolutely hate the Bonus/Penalty dice mechanic. It takes an otherwise a great game system and makes it clunky. I wish at the very least that this had been made an OPTIONAL rule.

Stats changed to percentiles: Whats wrong with a STR score of 3 to 18? After 6 editions why change it be 01 to 100? This seems like an arbitrary change made to create the illusion of an "overhaul" of a system that worked great before. This change was completely unnecessary.

Other than those two things, its a fantastic game. Heres to hoping they fix those garbage changes in the 8th edition.

I really wanted to use this product in my Roll20 games. Unfortunately, the files already have big bright thick grids on them. Which is terrible for VTT. Gridless map files are so much easier for Roll20 because the user can put their own gridlines and make them has bright or dim as they like. PLEASE update this product to include both the gridded and gridless map files.

This is one of my favorite OSR adventures. I absolutely love it! Its a great dungeon crawl with some great villians and awesome magic items.
