the game itself is great, no doubt I own the original DVD retail version and for convenience reasons this one here published on GoG , the are some graphic issues regarding first person view and sudden brightness changes that I didn't have in the original version in addition, for whatever reason there are some parts in the game where your character can't seem to pass through, e.g. the mountain slope in "a Vintage Year" leading to the docks, a car in the parking lot of "Dance with the Devil" close to a police officer smoking, you can't sneak up on him because you're stuck in between the car and the wall furthermore the AI seems to bug out sometimes, don't know if that is GoG specific or not, unrealistic enemy AI behaviour where they're able to track you down with 100% accuracy no matter where you are on the map, even if you're hiding in a closet, it's almost eerie lol so all in all just a rant over technical issues, the game still holds up to this day, big replay value even though I played it through a hundred times, whether you want to try out different approaches or just run and gun down levels
