I played it for a few hours myself over the weekend. It really does get across the zombie infested mall scenario very well indeed and is lots of fun. At times there must be a good hundred zombies on-screen. Anyone who likes flicks such as Dawn of the Dead will be in their element with Dead Rising.
I'm probably going to buy it, but will first wait for the reviews to see how well (or badly) the 15 minutes of carnage in the demo translates to an entire game.
Here's the Dead Rising map apparently. The demo is only limited to Paradise Plaza, which looks to be about 10-15% of the overall map, so there looks to be a whole lot more to explore in the full game.
