Beat the Steam version multiple times and it certainly lives up to the hype, whenever you're able to get it running smoothly that is. I was excited to finally try the GoG version but couldn't make it through another full playthrough because of the constant crashing. This GoG version crashed well over 40 times during 50+ hours of playtime before I had to call it quits. Most common is whenever I enter a new area or building I would get stuck in the loading screen which is extremely frustrating and killed the immersion for me. Other times the game would just shut down or freeze whenever I'm in the middle of a fire fight. I shouldn't have to install mods to fix a product I purchased, especially one that's been on the market since 2010. With that said, the story, characters, DLC & exploration is some of the best you'll find in a game bar none. The branching storyline with choices that actually matter is done beautifully. It's an amazing game but poor optimization poor hurts it.
