Lol I have never been able to completely play through an entire Fallout game before - eventually my savegame gets stuck in an area where the next interaction with a person causes the game to crash. I'm so glad I try games before I buy them - these developers never saw a cent from me, all these years. Uninstalled immediately.
On the other hand, I've tried Far Cry series of games and went right to the Ubisoft store to purchase a legitimate copy. Some may complain about those games, but at least I could play them without crashes.
