This game combines a couple of rare properties.
First, it's a competitive fantasy RPG......awesome.
Second, the barrier for entry regarding both cost and and the system learning curve are quite low.
The system is simple, fun, and easily expanded upon, should that be needed. The game is fast-paced, and doesn't take long to play, making it a fantastic pick-up game.
Also, you can't beat the price! There is a free version, however, this game is well worth the $3!
I, personally, will keep a copy with me if I go anywhere near a convention.
Troll in the Corner is definitely establishing itself as an indie game publisher that I'll be keeping my eye on.
