"Rock it" Schematics - 1100 Bottlecaps Using "Rock It" Launcher to nuke mutants - Priceless!
You will find yourself making choices with very real consequences that affect the progression of the story. I can definitely see myself playing through this several times with entirely different outcomes.
Of course be reminded the overall story, though extremely well done, is pure apocalyptic fantasy. As grim as the Fallout world is, in the true aftermath of a full scale nuclear war you would be playing as a cockroach. Surviving humans, if any, wouldn't look so well fed, even the tattered remains of cvilization reflected in the game would be absent, and downtown DC would be a glass table top. However that would be a lousy video game, so I'm happy to suspend my disbelief and enjoy the heck out of this game.
Even if you have never played any other RPG....play this one. It does so many things so well you just won't be able to stop playing.
