Touch Fighter is a 3D space shooter using OpenGL technology. You use the iPhone's accelerometer to steer (via moving the device around) and touch the screen to fire. Our friends at Engadget (who are liveblogging the event) also noted that an optimization screen showed it was running at an impressive 27 to 30 frames per second.
EA's Travis Boatman took the stage to show off the company's first product to come out of the iPhone dev kit, Spore. Initial pictures indicate that it's the mobile version shared by other cell phones. You use the accelerometer to move your creature and, of course, there are customizing options as well. [Update: EA confirmed that Spore for iPhone should be out in September, and that they're "actively using the new iPhone SDK to develop games for the iPhone OS." John Riccitiello, CEO of Electronic Arts, said, "The animation technology in the iPhone OS enables us to build awesome games. I think iPhone consumers are going to be blown away by the games we create for this platform."]
