I doubt I'm a minority when I say Bioware and Valve. Also adding Blizzard and Bethesda, and Obsidian is very close to being one. All of the employees from Obsidian were in great companies (Interplay and Black Isle), and NWN2 and KotOR 2 were both good, so as long as Alpha Protocol and Fallout: New Vegas are good, they'll be one as well. (And I highly doubt they can screw up Fallout, they technically have more history with the series than Bethesda.)
