Yags is designed to be a flexible game system that can be used with a wide variety of settings and genres. This approach can give an unsatisfying feel in some cases, especially if the game system isn't designed for a particular type of playing style which it is being shoehorned into.

For this reason, it should be made clear that Yags is designed for realistic/cinematic styles of play, where characters are either relatively normal people, or at best highly skilled and above average individuals, but with no special super powers. It should be possible to run stories similar to Die Hard or Kill Bill, but something like X-Men or The Matrix could be difficult.
