This is a great game - simple, well laid out and very flexible.
I've used it for both a basic dungeon crawl and also as a set of small scale sci-fi skirmish wargame rules and it handled both quite well.
I understand there's supposed to be some genre specific variants released in the future but you don't need to wait - modifying to fit a given genre is already provided for in the rules, it just takes a little thought.
Highly recommended! (and free!)
