This is Fallout. This is "the" RPG to own. It has withstood the test of time, and is still an excellent game to play, with a lot of different choices to make, hence a lot of replay value. The Fallout universe is so unique and nothing has come close to the Fallout series in terms of atmosphere and losing onesself in a game world. The Fallout series' intro FMVs are still awesome, too. I would reccomend purchasing it, but I expect most people on GOG already have.
