Fragland: "You also need to activate the game through Steam (even if you don't buy it online). As such not a problem if it weren't for the fact that it took me hours to get working as one problem after the other came forward. Problems that wouldn't have happened if I could have installed it in the traditional way.
In short: stay far away from this PC version. If you're interested in the game itself then it's better to opt for the console version."
