As the creator of the famed Grand Theft Auto franchise, Dave Jones knows a thing or two about wide-open game worlds. It's not surprising, then, that the first game from his new company Real Time Worlds takes place in a giant, persistent city that's filled with criminals. However, Crackdown is a far cry from the GTA series, in that you'll actually be playing as part of a peace-keeping force. Of course, this doesn't mean that you won't be causing widespread mayhem. In fact, during our hands-on time with the game at a posh San Francisco, we did some pretty insane stuff, which made us wonder if the city's denizens would have been better off just dealing with the criminal element surrounding them.
