im surprised nobody said rockstar yet :P

That is surprising...

Nintendo

Maybe an indie co...they have a smaller budget but with a small budget they can be really creative...

I'd go for Nintendo. As an industrial designer, I'd LOVE to be involved in all the creative process that goes into their controllers. Also, I'd get to work with Miyamoto-sama!

Who wouldn't want to be part of innovation?

Since Looking Glass Studios no longer exists... I'd like to work for Irrational Games.

Blizzard. Maybe I could get them to make StarCraft faster.

Bioware

Bungie

Rare

The only dev I could imagine is Bethesda, but I would demand to be on the Elder Scrolls team and nothing else.

I could work for Starbreeze in my home town, but I don't like their games.

I'm not super interested in game development personally. I would never accept to be a so called grunt (who fixes generic stuff with textures, fixes the mistakes of others etc). Programming, AI is quite boring too. But I could do music and sound, level design, modeling or artistic but I'd really like to be something high up in the hierarchy where you really have influence over the game, like project lead lol.

The developers of Gears of war..
