According to my final count:
Nintendo, EA. and Microsoft are the best publishers. (Tied for 7 games)
Nintendo is the best developer. (5 games)
Nintendo > BioWare > Bungie = Naughty Dog > Blizzard
PS3 > 360 (32 games to 31)
PS3 and Wii have the most exclusives on the list (6), but the 360 and the PC tie it if we include console exclusives or versions that are so much better they may as well be exclusives (Crysis, Team Fortress 2).
