Too many things wrong with it.
- resolution is stuck at a lower resolution. A mod fixes this, but it affects text. I can understand that each new game has bugs, but this bug should have been caught during testing, because it's so obvious.
- the graphics and animations are bad, this is 2012, we shouldn't have to accept this and the excuse "it's a small company" is weak, as proven by games like "Call of Juarez: Bound in Blood" by Techland, Orcs Must Die, Trine and Hard Reset.
- the GUI is awful. Nothing in the GUI seems intuitive
- awful mouse controls, too sensitive and there is little you can do about it
- most illogical use of a keyboard in gaming history. To give you two examples: Q to open a door or check for loot, END (yes, the end key, can you believe it) to go to the main menu and inventory. Yes, you read it right, you need to press END to check your inventory.
- the game can basically only be run with a gamepad and the irony is that PC gamers that avoid consoles have done this partly because of the fact that they hate gamepads
- locked frame rates, dropped frame rates
- other technical issues, like the game automatically restarting after quitting it.
The common excuse people have is: "You all wanted this game to be ported, so be happy you got it".
There is only one substantial point missing in that argument; people paid $40 for this game.
