The whole point of buying GOG games is to be able to play without DRM, but this game expects you to have GOG Galaxy or else and guess what isn't compatible with Linux? -_- Taking my money back.
I couldn't launch this on Windows or Linux, and currently investigating the issue with my Linux machine because I think this game may have contributed to the death of my 3 month old motherboard. I'm treating this game as if too broken to work without destroying hardware until I can prove it otherwise on my end. Avoid this game.
I remember playing this game years ago on Steam. It was always a fun romp playing as a slayer. Even though the character creation and skill tree was pretty limited, the story was always engaging. It felt like the further it progressed the more the game impressed me, and I just loved the game. However, something happened between then and now to where the game has some serious bugs to the point where it won't even load anymore. The steam version also has this issue and I'm very saddened by this. I do hope this game gets fixed soon. I want people to discover Larian's older games and it's not possible to explore this one in it's current state. I do recommend playing Larian's other games though. They're all very fun.
