The number one gripe about GC2 on Steam
http://steamcommunity.com/app/202200/discussions/0/540737414462276019/In my opinion, seems to be the barely playable state of The Ultimate Edition. See external link for example.
Look, never mind updating the game executable, we've been down this road before. What about an official data patch? Same effect as the various mod patches, but it goes out to all the Steam customers, they're moderately satisfied, you only need to spend a moderate amount of time on it, and the issue is more or less settled.
Honestly, I don't really mind either way, but I feel obliged to point out that a satisfied customer is a good way to bring in more customers. A dissatisfied one can put a damper on future sales.
