I like Gearbox because Randy Pitchford personally called me out for being an asshole and made me re-assess how I act on the internet.

Story time!

[Cripplegate]

Rare - Viva Piñata.

Would also be my answer. One of my favorite games period.

I also enjoyed Kameo more than any of their N64 adventures (Banjo, Donkey Kong 64) or other collectathon monstrosities like that Star Fox jank.

[beelzebozo]

rare.

BLAST CORPS.

[br0ken_shad0w]

Crystal Dynamics - Gex

Fireaxis Games - Sid Meier's Alpha Centauri

[Solid SOAP]

SNK for Metal Slug, I love that series so much, it's a shame they don't really back the franchise so much anymore.

[Heart of Black]

Pursuit Force. My pal Shane Bettenhausen was absolutely confused when I mentioned that, but yeah. Best Sony IP, EVAR.

[Glass Rebel]

DICE for Mirror's Edge (known for Battlefield)
Raven Software for Singularity (known for Hexen/Heretic, Soldier of Fortune)
Camelot for Golden Sun (known for Shining series)
Treasure for Sin & Punishment (known for Gunstar Heroes, Guardian Heroes, Ikaruga)
Kojima Productions for Boktai and Snatcher (known for Metal Gear)

not to say I don't like their other games but these take the cake for me

[FateBreaker]

Koei. Destrega.

Lionhead. Fable III.

[TruePrime]

From Software.

At least in the west they are now known mostly for the Souls series, and I couldn't careless about those games.

ACE 1/2/3 however are fucking amazing (1 Doesn't hold up after the awesome improvements of 2 and 3 though) and if they can somehow make a game on that level and not the awful R/Portable it would likely be my favorite game this gen.

[Tizoc]

I love Capcom for the Gyakuten/AA series and Ghost Trick.
EDIT: Oh and Namco for Klonoa.

[AAK]

CyberConnect2 - Silent Bomber

This.... but I don't really care for them anymore.

Also:

Naughty Dog: Jak 2 and Jak 3 ... That was ND at their prime not counting their cutscenes and dialogue.

[Fjordson]

All of their franchises are pretty damn popular, so I don't know if this counts, but I'm a pretty big fan of Valve despite not really liking Half-Life. Half-Life 2 especially has always been kinda boring to me.

But I love Left 4 Dead, Portal, Counter-Strike, etc.

[daxter01]

Naughty Dog-Jak series
Rockstar- Red Dead Redemption

[Sojgat]

Treyarch - Spider-Man 2

100% this, the best game they have ever made.

From Software - Otogi

Edit: Crystal Dynamics - Soul Reaver. I think Legacy of Kain series has already been mentioned but I just love this game so much in particular.

[Capndrake]

Enix for Soul Blazer, Illusion of Gaia, and Terranigma (Rather than DQ).

[Dog Problems]

Capcom. They're mostly know for Resident Evil, Mega Man, and Street Fighter but what comes to mind when I think of them are their beat'em ups. Particularly Final Fight 3, Aliens vs. Predator, and Battle Circuit.

[TheOGB]

Camelot for Golden Sun (known for Shining series)

Oh man, these guys for Mario Tennis on GBC for sure

[KongRudi]

Codemasters for the Dizzy-franchise. :)
I also used to like Raven Software when they made their own games, like Black Crypt, but stopped liking their games when they became ID's port-slaves, and started using ID's tools.
I also liked Dice's Pinball Fantasies and Deluxe, but not any of their newer stuff.

[Sintoid]

DICE Mirror's Edge is a brilliant game. I couldn't give two shits about Battlefield.

This for me too

[abusori]

Not a company, but a person: Hideo Kojima. I haven't enjoyed a Metal Gear game since Metal Gear on the NES, but every other game of his not in that series I enjoyed and Snatcher is still one of my favorite cyberpunk genre games.

I love Boktai so so much.
That's what I know Kojima for; I haven't even played any other games from him.

[King of the Potato People]

Eidos, Legacy of Kain

[Muchi Muchi Pink]

SNK, but not for any of their many, many fighters, just Metal Slug

Kof and Metal Slug are their biggest franchises. So huh?
I love Cave for Muchi Muchi Pork.

[Guerrillas in the Mist]

Irrational's best game is SWAT 4.

*Bro-fist*

[beril]

Yuji Naka for NiGHTS rather than Sonic is the obvious one I guess
And TriAce for Valkyrie Profile over the crapfest that is Star Ocean
And Team Ninja for Other M

[FieryBalrog]

Valve for Portal & Portal 2. Never really got into HL1 or 2 despite trying.

[Xater]

Irrational Games:

[NaviLink]

Hasn't been mentioned yet I think : I love Omega Boost from Polyphony Digital.

[eso76]

Cliffy for JazzJackrabbit or whatever.

i'm joking.

[K.Sabot]

Namco for Tales.

[beril]

Rockstar for some of the classics from their DMA Design days; Unirally in particular and Lemmings obviously

[ULTROS!]

Arc System Works - Hard Corps: Uprising - They should do more 2D non-fighting games.
Namco Bandai - Tales and Xenosaga (RIP)
Konami (well before) - Silent Hill and Suikoden

[TucoBenedictoPacifico]

Irrational Games:

Hell, I was going to post this. D:

Also, if DEAD developers are a good choice...
Everyone apparently remembers and loves Microprose for Civilization or their flight simulators, but, even enjoying those, their best game for me was this babe:

[Syril]

Epic for Unreal and One Must Fall 2097.

Silicon Knights for Dark Legions.

[RawPower]

Konami for the Ganbare Goemon series, and their abundance of 16 bit classics. I dig Castlevania too, but I couldn't care less about Metal Gear (beyond MGS 3) or Silent Hill.

[wwm0nkey]

From Software for ChromeHounds.

[walking fiend]

Bungie for ONI~

This, so much THIS!

[Alrus]

Sonic Team for Phantasy Star Online. (I never liked Sonic games)

Lucas Art for Day of the Tentacle (I liked it better than any other adventure game)

[jimi_dini]

Grasshopper Manufacture for Killer 7

[Dragoon En Regalia]

Artdink for their A-Train games and other old and great PC sims, all of which have been glossed over by fans in favor of the Kazutoshi Iida games and Carnage Heart. An actual shame.

[djtiesto]

Irem for Kickle Cubicle and Yanchamaru (aka Kid Niki). Never played an R-Type game. Epic Games for One Must Fall 2097 and ZZT. I don't particularly care for what they make currently.

Kudos for mentioning ZZT, yeah what a long way Epic has come... but damn I first learned how to do extremely basic coding and level design thanks to ZZT's editor. Also love Epic's Unreal Tournament series but couldn't care one bit for Gears.

And like others said, DICE for Mirror's Edge. Have no interest in the Battlefield series whatsoever, it looks like the posterboy for everything I hate about this gen. But Mirror's Edge will go down in the records as a classic.

And finally, RARE for Snake Rattle 'N Roll and the Wizards and Warriors games. Their N64 lineup never really appealed much to me as most people, nor did I particularly care for the DKC trilogy.

[bede-x]

Square for Vagrant Story. Much more interesting and mature than many of their other series.

[LiQuid!]

Obsidian for Alpha Protocol. Warts and all it's still probably my favorite RPG of this console generation and I think it's criminal that those dudes have been relegated to crapping out sequels to other peoples' (namely Bioware's) shitty RPGs for years.

[ArisenDragon]

Shenmue by Sega considering they haven't made a third one yet. I really really hope they do it.

[fart town usa]

They didn't develop it but I always associate epic with Tyrian.



This one as well

[InfiniDragon]

Enix for Soul Blazer, Illusion of Gaia, and Terranigma (Rather than DQ).

This.

Also, From Soft for King's Field (though I do also love the Souls games), and Capcom for Breath of Fire: Dragon Quarter.

[Seth Balmore]

DICE, not for Battlefield, not for Mirror's Edge, but for Pinball Fantasies, Pinball Dreams and Pinball Illusions. Many childhood hours were spent playing those.

Enix for Bust a Groove 1 & 2.

Capcom for Shu Takumi's games (Ace Attorney, Ghost Trick) and nothing more.

[Tellaerin]

Not a company, but a person: Hideo Kojima. I haven't enjoyed a Metal Gear game since Metal Gear on the NES, but every other game of his not in that series I enjoyed and Snatcher is still one of my favorite cyberpunk genre games.

Hear, hear.

Though in my case it'd be Kojima for Snatcher and ZOE2, to be specific.

[Celine]

Enix for Soul Blazer, Illusion of Gaia, and Terranigma (Rather than DQ).

Enix isn't the developer of those games.

[RurouniZel]

You know, I think I'm going to have to go with SEGA on this one. I LOVE Valkyria Chronicles and Yakuza, and they've recently impressed me Binary Domain but I'm pretty hit or miss with the Sonic games. Sure, I've played them but Sonic is definitely not why I like the company.

This. I love Sega but it's mostly other stuff like Sakura Wars, Skies of Arcadia, Valkyria Chronicles, and Project Diva/Mirai that I love them so much. <3

[pvpness]

I loved Blizzard so hard for Blackthorne. That and Rock 'N Roll Racing. Soooo great. Modern Blizzard is fail.
