Which game publishers/developers do you guys like the most

Sega, because gotta go fast.

Wadjet Eye Games and Valve.

Valve just can't make a wack game. They just can not. Even though I don't really like CS.

And Wadjet Eye care about their fans and if you listen to the developer commentary during their games you'll see how dedicated they are to this (mostly Dave) and how much they/he care(s) about their/his fans.

Softstar Entertainment Inc.

Eggsoft. Because they're the last developer around where I will autobuy their games.

Klei Entertainment has made some really interesting stuff I think (:

Grasshopper Manufacture

Cave

Treasure

Capcom

Atlus

Clover (RIP)

Xseed

Team ICO

CD Projekt RED

Ubisoft Montreal

Poor THQ. They could've been the best PC games publisher, but then they threw it all away.

CD Projekt

Klei Entertainment

Gaslamp Games

Off the top of my head...
Valve
SubSoap
Frictional Games
DoubleFine

Either because they take care of their fanbase, or they have interesting games designed more for player enjoyment than for profit.

I like Nintendo, Treasure, Valve, Sega, Natsume, LEGO Media and Konami because yes.

Valve, Eidos/Squeenix,CDPR

iD Software

Publishers:
Valve (Steam - lol!)
Square Enix (recently they've been releasing some really nice games, that had great PC ports)
Cenega (local distributor and publisher - they're just doing a great job, offering nice deals, etc.)

Developers:
Valve (great games, great software)
Eidos Montreal (only one game made so far, but we just don't see many complicated project as this... and they're apparently making Thief 4... hopefully)
Frictional Games (I just have a lot of respect for them and what they do - keeping Horror Genre alive)
Flying Wild Hog (favourite local developer... one of few devs, which made a shooter as hard as it should be, without making it too unfair... oh and CDPR is overrated)

I use to love Bioware, until they throw ME3 ending at my face. Buy i still love them
I use to love EA too, back on the day of game still use disc to install and explansion . Ea release a lot of good game

Valve and... I don´t know, all has good and bad games...

Crytek for Crysis,Raven Software for Singularity...

Daedalic, for keeping the adventure and point-and-click genre alive, beautiful and fun :)

Bethesda , Valve , BioWare , Blizzard.

My favourite developer was Pandemic Studios. I freaking loved Mercenaries, DAH, SW: Battlefront, and the rest of their games. It sucks that EA shut them down, I was looking forward to The Dark Knight, which was an open world Batman game, and Mercs 3.
My favourite publisher is probably Square Enix, only because they haven't turned into another EA... Yet.
Although, it was THQ, until they went bankrupt.

Favorite publisher is definitely Xseed. They bring us so many awesome games and care about their fans. I love how well they support releases and you can see their sheer love for the games they publish shine through. So wish more publishers were like Xseed.

Favorite developer is Nihon Falcom. Mostly because they make my two favorite game series, but also because they are one of the few devs out there who still know what makes a good game and they won't bend from their ideal of a great game in any way. They don't care so much if the game has the newest and shiniest graphics, they care that the games are fun to play and have an enjoyable story and characters. A player knows when they pick up a game by Falcom that it will have great gameplay, awesome music, and a rich and detailed setting with interesting characters.

2K, Bethesda, Valve, Konami...
