Jeez, how in the heck did you not list Ubisoft? Ubi + Conduit would be a match made in heaven. Ubi is responsible for bring us No More Heroes 1 & 2, Rayman Origins, and Red Steel 2, 4 of the best games on the system.
That being said... Retro is God's game developers right now.
Retro > Ubi > Non-Retro Nintendo > everything else.
