Shadow Cities is an interesting title from Finnish developer Gray Area. It's a location-based MMO, in that you level up a character while fighting with other players and claiming territory, all of which is based on the real world around you and your iPhone. The game allows you to cast spells with special gestures, which are resource driven and set up to play long campaigns in small bursts of time -- it's designed perfectly for the iPhone and its various interfaces. I found the game a little confusing when I saw it at GDC, but that was an earlier version. Even if the game is a little complicated, it's rewarding when you figure out exactly what's going on.
