Thanks to the glory of the Order of the Stick, I have just learned of the existence of the Edition Wars. If you, like me, are one of the few people in the gaming world that doesn't play D&D, then you won't know that apparently there are heated debates raging across the internet about which edition of D&D is better. Personally, I don't care; if I'm going to play a fantasy game, I'd rather play GURPS.
Anyway. In googling the Edition Wars to find out more about it, I encountered an argument between two players. A minor point of the argument was one debator was saying that he feels that in 'modern' gaming (as he calls it), there is too much of an assumption that the players will succeed. He feels that at no point is there consideration that the players will fail. This is a problem primarily because the players, under the belief that the GM will not allow them to be unsuccessful, enter situations that are too risky for them to handle.
This is an interesting viewpoint. I don't know if it says more about me that I've never made that assumption, or if it's just proof that I'm an 'old-school' gamer. But either way, it seems like a silly assumption to make.
