honestly, I cant answer straight this question.
Rockstar, Nintendo, iD Software, many more brought me many awesome games.
But most of them now arent even close to good and I dont really have the will to play their newest games.
And the older ones slowly take same path. Except Doom, from ID software.
So my answer is: ID Software.
