Great game, keep in mind it is a straight port of the xbox 360 version.
The good:
+New content to play, 10 to 12 hours :) with new bosses (really well done and hard ones) enemies, armors, rings, weapons etc this is amazing!
+It is finally on pc
+Pretty stable game, port but stable.
The bad:
- Unplayable with keyboard and mouse, really it is unplayable. Keybinds are really bad for default and the game was made to be played with a joystick and this wasnt fixed or changed for the pc version, so buy a joystick or dont buy the game
- Capped frames to 30, again this is for the port.
-Without a fix if you put a higher res than the default one the game will look like crap and will have severe framerate drops, this is fixed with the fix from DURANTE
- The game only works good with an xbox 360 joystick, if you use other joystick the buttons and the analog pad will go crazy, again you can fix this with a free program called x360ce
- Game for windows...
And that's it, I cant give it a 10 like the 360 version but I will give it an 8 because the bugs are fixable and I hope they release some kind of patch an official one...
