Better Zombie Game: Dead Rising or Left 4 Dead?

[Skeeuk]

L4D is a good multiplayer game, you may even like it in single player.

dead rising, although a good game, its spoiled with one of the most ridiculous save systems ever devised. the game forces you to rush through and if you dont make certain checkpoints in time, you will never complete, so its a start all over again.

^thats the only thing that made me quickly trade back in dead rising.
