So far, on Windows 10 the game is constantly crashing - it didn't even launch without having to download unofficla c-1 launcher, which fixes the exe files of the game. This should be already done by Gog. After starting playing the game, the game is still crashing randomly - sometimes after 15-30 minutes, sometimes instantly after loading saved game. As I have found on the internet, the crashing of the game is well known fact with multiple workaround being discussed. Yet Gog.com version is plagued by these issues too. As this game can't be even launched with the Gog.com launcher, I can't recommend it.
