After almost 20hours over the course of nights (After work) of messing around with my Steam version of this game, going through countless versions of "Easy Fix" for the Games for Windows Live issue and "xlive.dll" missing problem with constant frustration really wanting to play one of my most memorable games from the 360 era, a game I probably spent a good 700-800hours on wondering around hunting down every unique item I could, and REALLY REALLY wanting to play this game again (After 7years?) I had two options either dig out my Xbox 360 and hope it didn't have red ring of death (and deal with all the bad stutters and random crashes and low FPS it had) OR re-buy the game on GOG, after reading about so many people going through the same thing as me and trying everything they could to fix the Steam version of the game, I decided to purchase the game on GOG and pray for best. BEST DECISION I MADE THIS YEAR SO FAR! You purchase the game > Download it > Play, runs smooth, no stutter, no GFWL Crap. Runs and Plays like a dream, now i can go back to being that crafty sniper with 10 agility and 1 intelligence. TL;DR - Amazing, So happy I fount out about GOG.
