Although generally known for top-of-the-line 3D games, id software's John Carmack has become a passionate iPhone app developer. Per Kotaku, Carmack has personally cited the platform as a return to the older school of game design, where a single enthusiast can turn out a great game in a matter of a couple months, id software’s iPhone ports of Wolfenstein 3D and Doom were basically pet projects of Carmack himself.
Carmack has recently offered the following: "Apple doesn’t give us anything ahead of time either, so haven’t put hands on it ourselves, but we certainly are expecting to try to have our Rage title for the iPhone, iPad, whatever, working across there."
