For what it's worth, all versions of the game should be essentially the same. Not sure if the Steam version has any significant differences.
To everyone playing a pirated copy: do consider supporting the devs, if you enjoy the game. If you can't afford buying a full price copy, buy one in the future if you can, once it's offered at a discount.
gunsynd: Sure,but people do not like Pirate talk here.
sariaen: He bought the game right? :D In my book he is cool :) Besides, why there are no demo versions so that PC gamers can check if the game is interesting and if their setup is powerful enough to run the game at acceptable quality?
Yeah, that's a shame, about the lack of a demo or benchmark; I would have liked one as well. But at least now that the game is out, it has been tested on many different graphics cards and hardware configs, and with a little research you can get a good idea how the game is going to run on your system.
