To play the Fallout franchise, you have to have an incredible appetite for RPGs. The turn-based game-play, S.P.E.C.I.A.L. leveling system and character setup can be frustrating to some people. I am no exception. I didn't pick the right stats, and the game has been much more frustrating than it could have been.
Wide, expansive universe, kill-anything-anytime-anywhere-and-loot-their-body abilities are a MAJOR plus, as some RPGs have your attack abilities confined to hostile units only. Black Isle has also released the game Lionheart: Legacy of the Crusader. Another fantastic title released sometime after Fallout 2, with improved game-play.
Fallout 2 is a fantastic game, but I must warn any non-RPG buffs against this title, as it will frustrate the living hell out of you.
