Performance Issues
Gameplay Options
Hardware Support
Documentation. . .

The list could go on, but that's not really helping anyone. The devs know what needs to be done (at least I hope they do) and it's in their hands, if they want to give us the game we asked for (in a completed state) or just do a shoddy patch-job and move on to another 1/2 finished project (BOM).
