Do you want us to do it by genre like you did?
Driving Game - Polyphony, of course
FPS - Infinity Ward and Guerrilla Games. IW to make a great shooter, and GG to make it more realistic and better graphically. Also GG will be in charge of patching the game since it takes IW months to fix big problems (like the fucking unlimited care package glitch)
TPS or Platformer - Naughty Dog
Stealth - The guys who make Splinter Cell
Open World action - Rockstar and the Guys who made Driver
RPG - Bethesda, by a mile
