The game probably works fine for most people, but my computer has a problem with Unreal Engine which makes the game constantly write massive amounts to my SSD. This makes makes any Unreal game unplayable. First the noise is really annoying, I have to use headphones. But even with that, I don't want to kill my SSD drive.
I bought and played this game only for a couple of minutes before I got bored and the game crashed because of lots of bugs (they might fixed the bugs in the GOG version thou). Its 3D graphics are worse than the older X-COM games with 2D graphics. The gameplay and atmosphere is no way near the original X-Com.
