CD Projekt RED. Not many games yet sure, but their (so far) consumer friendly attitude towards DRM and DLC, and single player championing. The game I am most hyped about by far is Cyberpunk 2077, not really going on anything other than a sci fi rpg based on tabletop game from the guys who made The Witcher games, yes please.
Bethesda before they made Skyrim and approved of ESO.
CDProjekt now, they released The Witcher 2 Enhanced Edition content to all owners FOR FREE that had bought The Witcher 2 earlier on. They also did this with The Witcher 1. The Witcher 3 will not feature DLC, micro-transactions, they're offering a true next generation experience and not trying to cash in on last generation console owners, so that won't drop set them back from making the best game they possibly can. They're also DRM free on PC and approve of the modding community for their games (even hired a modder for their combat mechanics I believe).
Honorable mention: Rockstar.
