I would probably say Rockstar, to be honest. Everything they have released I have enjoyed, except for Manhunt, since I'm not really a big fan of games involving stealth. Most of the franchises Rockstar publish games for I enjoy. I mean, I owned Midnight Club 3: DUB Edition, but that didn't stop me also buying DUB Edition Remix since it featured the city of Tokyo, a few new cars, and a few new tracks in the soundtrack. Maybe I'm strange for that, but I wanted more from the Midnight Club experience.
The only game I've played on the current generation of consoles from them that I wasn't as fond of was Red Dead Redemption, and that's only because I prefer the Grand Theft Auto series. I still consider RDR to be a fantastic game but having played Grand Theft Auto, I simply preferred the series I was more familiar with. I admit Redemption was fun, and the story was good but it didn't feel like there was a reason to come back to it.
I'd still buy another Red Dead game if Rockstar decided to release one, though.
