I have a lot of devs I like, but these four are the cream of the crop to me:
Nintendo EPD
Turn 10 Studios/Playground Games
Bethesda Game Studios
Rockstar North
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
