I mean company, not person. I'd have to say Bioware. The only game that they've released that isn't an A title is the recent Sonic Chronicles.

Lionhead Studios

their games are so detailed and interesting to play, since not everyone can have quality and quantity, they seem to focus more on quality.

i have to say blizzard.
i have always loved starcraft,warcraft and diablo series

In harsh times, the strongest currency is cooperation.

It's hard to limit it to one. These five are probably my favorites though:

Intelligent Systems
Nippon Icchi Software
Namco Tales Studio (formerly Wolfteam).
Tri-Ace
Square

Tree + Taco = Tree taco.

Second Square, not only for the FinalFantasy games
Maxis, thu i wish they hade never made The Sims

I'm sorry, llofk, but you definitely don't know their track record. They're quite famous among the game industry for releasing unfinished games and going back on their promises. It's true that their games are often fun to play, but one has come out unfinished (Black and White 2), and two are not what was promised (The Movies, Fable). They're rated low.

I'd have to say my favorites are Bioware, Valve, and Blizzard has a huge commitment to quality that deserves attention. Nintendo also runs a very good ship as well, but their name is often smeared in the stupid System Wars. It doesn't make sense, since Microsoft doesn't really make their own games, and Sony definitely doesn't.

hard decision.... but if it has to be for multiple games not just a favorite, treasure
namco and squaresoft are close seconds(not squarenix, too many beltz and zippers now)

Never been too fond of the NA developers, too money oriented and not my style of games.

Good ones I like since there's no clear favorite,

Cyber Connect 2 (also known as CC Corp in their .Hack games).

Namco Bandai

Nippon Ichi Software

Atlus Co (for their persona series)

These are the ones I can point out more easily than others, SE isn't bad but the FF series isn't that big in my books, love the Dragon Quest series though.

Square-Enix
Vanillaware
Nippon Ichi
Bioware

Bioware by far, (they also have a nice forum)
Blizzard for obvious reason
LucasArts...only for making Monkey Island
Relic

I don't know if you mean what I think you mean, but if you don't think eastern and European (Yeah, Europe has development companies too) aren't interested in money, you obviously haven't seen the litany of crap games that are equally prevalent in all markets. You're being a little naive...

We weep for a bird's cry, but not for a fish's blood. Blessed are those with a voice.

Arc System

"I am who I am because of who we all are"

Bioware, Bethesda, 2K Sports, Infinity Ward, Insomniac Games, Epic Games...

Just because someone's head was chopped off doesn't mean they're dead. That's just silly.
