Who is your favourite game developer?

Ubisoft :D
assassin's creed, and all those good games.

I can't go with specific devs but definitely with some publishers. Bethesda an 2K always were somewhat of a guarantee for a good game or two.
Lately I've seen a lot from Devolver Digital so I'd count them as well.

my all-time favourite would be Bullfrog. not sure, which current studio deserves to take that spot.

Paradox Interactive are my fav

Treasure, Lobotomy Software, Westwood Studios, LucasArts, Sega (Sonic Team, AM2).

Oh forgot Looking Glass Studios!

Deep Silver or 505 Games....tough choice mate!!!

Ubisoft, Far Cry series and Rainbow Six

Ubisoft

I can't believe I forgot thatgamecompany!! Journey, man, Journey...that is a MAJOR life-affirming game!

Rockstar for sure ! They don't sh*t on their games !

Also Deep silver and 2K Games are great ones !

11 Bit Studios, not only for This War Of Mine, also for all the charity that they do

Grinding Gear Games (Path of Exile)

They interact with the community a lot. Always listening for feedback. Joking from time to time. They are constantly improving the game, making updates. There is always at least some sort of news every day (exept weekend). O, and the game itself is great)

Obsidian Entertainment

i play currently Borderlands, so i just say 2k. ;)
