idTech?

id Tech or a modified id Tech to make a new Quake Engine.

They’re a game studio, like the makers of the Unreal engine. They can make whatever they want. Id even has its own (old) engine and made many FPSs before Unreal was ever even conceived of.

I believe the thinking is that it will be hard to beat Unreal in head to head competition using their own engine. FPSs are already a poorly differentiated genre with tons of overlap, so its not hard to imagine their game being another “also ran” in a sea of “same old same old” FPS games.
