Game is so buggy it is unplayable on some systems. Other systems it runs fine. I would buy it here because GOG allows more time before it is unrefundable.
Spent the morning getting the circle of 8 modpack working... Took uninstalling and reinstalling a time or two, then tweaking the game to my liking from the in game options menu. If you are not lazy this is good deal on an awesome game. If you are lazy, just complain here like the rest of the couch potatoes. :):):)
In recommend buying this game here as GOTY edition is $45 at the time of this writing on steam.
