Not really RPG(well it does have stats and your guys go up in levels:)
But I found this computer version of bloodbowl and I always tried to play(could never find the people or give the time)
This game is pretty fun, thought I would share it with you guys.
I am playing a lizardman team in single player and starting a chaos team in multiplayer. Your guys can go up in level and get new skills and can even die in a match or be maimed.
I guess the easiest way to explain it is a fantasy football game...on crack. It's either turn based or realtime...I only play it in turn base.....
Check it out.
