This game is so immersive and full of everything, for me it should have won game of the year if only the devs waited until it was really finished (altough I enjoyed since it was first released, I don't understand why so many people complained). I don't like the second launcher once I launch from GOG, it really makes no sense to press play button and then another window pops where I have to press play again, that's just ridiculous.
The game runs well, I've played around 170+ hours and never crashed. In the other hand, I noticed many bugs or ingame errors. It makes sense since the game released when it wasn't done. I enjoyed the story, altough wish it had more content. Now waiting for improvements, more content and DLC's :)
