(dice being a good way to keep a game difficult/competitive, but not for mandating everything in the game. I haven't seen THAC0 in a long time and am grateful - moreso that it was removed in 3rd ed)
We played 3.5, and I was the only one that knew what THAC0 was. This one is story driven. We only had two fights, and my character has been allowed to be kinda nuts. I hit a wolf with another wolf.
