Highlights include a video of the id Tech 5 engine (aka Rage) running on the iPhone 4G at 60fps, with claims that it also runs on the iPhone 3GS. Carmack noted that performance on the iPhone was able to 'kill anything done on the Xbox or PlayStation 2.' He also announced the source code release of two games, Return to Castle Wolfenstein and Wolfenstein: Enemy Territory. Also, Carmack finally admitted that Doom 3 was too dark!"
