Why is dead rising so entertaining

It's entertaining because you get to roam the mall and kill zombies in many ways. You can use any anything you see in the mall to kill them or you can fight them with karate. There are bonuses, like taking photographs and saving survivors. You can play the storyline, or just spend your three days killing as many zombies as you can until the helicopter comes back to rescue you.

Not to mention the fact that everything you see is a deadly weapon. My advice is play it on the computer and get the mods for pre-made weapons.
