Um...yeah that was my point: id, a developer which is synonymous with PC gaming, managed to completely botch a PC release under this publisher. ZeniMax/Bethesda is now known for rushing out every single game regardless of the developer and/or engine used. (the Bethesda developed Gamebryo games just happen to out-stink the other stinkers)
Honestly, Creation Engine(Skyrim) and RAGE-Engine(Rage) were both not really solid.
Unreal Engine has been quite solid and easy to work with for many companies, look at Unreal Tournament, Gears of War, Batman games, Borderlands 1 and 2 etc. All of em great successes on both PC and consoles. The largest worries are the Engine and the Developer, and thereafter the publisher.
