It was announced today that id, the company that invented the graphics-card pushing first-person shooter genre, has made the leap onto smaller screens with a new division simply called id Mobile, created in conjunction with Fountainhead Entertainment. The studio will be focused on games for cell phones, DS and PSP, with a few titles (like a mobile Wolfenstein) already in the works.
id and Fountainhead have been headed this way for a while, after Doom RPG and the Orcs and Elves games. As you've probably seen, most mobile games are pretty awful (something even id's John Carmack admitted to in this interview about the new division), but if anyone can turn that around, we have faith that Carmack's the guy. (Especially since the rocket thing didn't pan out.)
