This is a great game that strips the d100 tradition down to the essentials, but also adds some very neat approaches. The system is unified and able to model different kinds of styles and settings, though you as the GM will have to put in some work, which is par for the course with generic systems - for my part, that's my preference, but your mileage may vary.

The conflict resolution system is central addition to the d100 way and does a good job as a general approach to many different kinds of conflict. The fact that the game features a conflict system and not a combat system is a deliberate choice that is meant to reframe your thinking as a GM and with combat being just one type of conflict among many can be a strength or a frustration depending on your preferences. If you crave detailed and "crunchy" combat, this is not the game for you, but if you run a game where combat happens, but is not the main focus, then you have only one system to master, that is quite flexible in terms of granularity of narrative and mechanical detail.

Another strength of this system is the ease with which you can homebrew and make your own additions to the system. You can make a list of skills tailored to your game/setting, for example. Additionally, with it being a d100-system there is not really a reason that you couldn't convert material from other d100 games into Comae.

This game is more than worth the low asking price and it's a great choice of system to introduce new-comers to RPGs, since it's very simple and intuitive to grasp the core mechanic, but it's not so bare-bones as to leave your players "unmoored".

As a newcomer to the OSR style of play I appreciate Ben’s flair for simplifying game mechanics. Also this os more than worth the purchase for random tables alone which can be user with any other fantasy system. Highly recommended.
