Skyrim was a good game overall, and they kept patching it like they do with all Elder Scrolls titles and (although it was playable for me at launch) it rapidly improved. Rage on the other hand had a terrible launch all around. So while I like id, their recent efforts have involved a lot of floundering about blindly. At this point, Zenimax taking a more active role could only improve things, because there's nowhere to go but up. Doom 4 was so bad they had to start over.
With that said, I would like to believe id still has a future, given their starry past.
