I've only heard of three of those epic games... games. Unreal, Gears and Bulletstorm. Didn't know they developed Bulletstorm actually. Hadn't heard of those other games until now.
Pretty good list anyway. It's hard to argue with any of it. They're all major established studios with a great history behind them and a great future in front of them. The only one I'd question is Retro. Don't get me wrong, I respect what they did with Metroid and DKCR with an enjoyable game. I just feel like they're not... quite there yet.
Anyway, if we're all making lists, mine would be:
Nintendo
Everything, really!
Bullfrog Productions
Populous; Theme Hospital; Dungeon Keeper.
Psygnosis (Studio Liverpool)
WipEout; Colony Wars; G-Police.
Insomniac Games
Spyro the Dragon; Ratchet & Clank; Resistance.
Naughty Dog
Crash Bandicoot; Jak & Daxter; Uncharted.
Maxis
SimCity; The Sims; Spore.
Squaresoft
Final Fantasy; Parasite Eve; Super Mario RPG.
Valve
Half Life; Team Fortress; Portal.
Rockstar
Grand Theft Auto; Canis Canem Edit; Red Dead Redemption.
Blizzard
Warcraft; Starcraft; Diablo.
Haha, this literally made me just realise that Blizzard only have 3 IP's. Major IP's, but still.
