I play it all the time!
I like eventing and dming and building.
It was worth the twenty dollars.
Yeah, it was worth the money.
I'd buy the game again, if only to give the maker more money.
I'm just no good at T/DMs, and I can only build a couple of styles, and to be honest, I'm not the greatest at eventing, either.
Even when I played the game a lot, just about the only thing I did was talk to people and see what they made.
I really liked doing that, too.
I would suggest this game to anyone looking for a </=$20 game, I guess it's just not the kind of game for me.
