Quick Summary:
--------------
Alright, game is pretty good if you like zombie games. Dead rising is a mix of a semi-serious story with quite a bit of comedy to offset it. If you are looking for an extremely deep story with compelling characters this game isn't for you, the story is good its just not anything amazing. The real great part of this game is its gameplay allowing you to equip almost anything in the mall and the fact it has good replay value through different endings. Also keep in mind this game was originally released in 2006 and thus the texture equality and model quality of course isn't going to be outstanding.

Pros:
--------------
- Good 'Timer' mechanic giving you a sense of pressure in a apocalyptic setting.
- Allows you to pick up almost every item around you to use it as a weapon.
- Multiple endings.
- Lots of characters to interact with / fight with.
- psychopath system gives you insight into the lives of those in the mall.
- Comedy 10/10
- From my experience it seems that the game is a lot less buggy than its 360 version.

Cons:
--------------
- Survivor AI is beyond awful , they will often stop following you or get stuck.
- Psychopaths are often very easy to defeat after reaching a certain level in the game.
- The main game path doesn't change too much through playthroughs aside from the ending.

TD;LR - If you like zombie games and don't care about story too much go for it. If you are looking for a deep story maybe give this one a pass.
