Funny; I was thinking of writing a review for it.
Dead Rising has some absolutely brilliant dark humor and tons of new gameplay elements. And it's fun. Fun! Remember when a game could get away with not trying to be a moving epic or being some pencil-pusher's attempt at a gritty war-story?
That said, the controls feel like Capcom forgot they had more buttons they could use and are often stiff. The ally AI is dumber than a half-empty bag of rocks. The ranged combat feels terribly forced and stiff. There are many gameplay elements which do not feel as if they've been integrated very well into a whole. An initial walk-through of the game will likely end in a bad ending unless one is used to Nintendo-Hard difficulty.
Despite this, the game is still worth a play. The bosses are amusing, game play is addicting, and simply put, the game lets you suplex a zombie. A game where you can walk up behind a zombie and throw it back with a sickening, wet thud is -fun.- All the little quibbles disappear the first time you realize you can grab a ten foot cactus and use it as a melee weapon. Yes, you'll be grinding for levels in the game. Yes, the controls would be much better if they were tighter. And absolutely; hi-def is almost a pre-req. You will almost certainly have to replay the game a few times, though Capcom made a good move in unlocking new modes after you do so. At first, you can only play 72 hour mode, where you sandbox or else do the main story. If you complete the main plot with the best ending (and this requires hustle), then you may opt to enter 'Overtime' mode which concludes the story with one more 24 hour run through the mall. Finally, survival mode is true sandbox play, driven by a slowly draining health meter which you'll have to restore.
None of that matters after the first time you grab a scythe, pop a zombie in the knee, and as it falls down reap its head clean off.
