Fallout it's a game where the world has changed due to war and the radiation, now everything looks like a dead place, but of course, you're the hero (or the villain) of the game, you must save (o destroy) that chaotic world. The 2 first games was made around the '90 I think, it was a RPG with battles turns-based. Then later Fallout III was made, and now looked like a FPS-RPG game, the DLCs made the game even much better, and now we have Fallout New Vegas, a bettered version of Fallout III (Looks like a expansion pack at the start, but that doesn't matter)
Many thanks, mister. I dunno, I may get into this. The few videos I've seen seem rather fun. Especially the part where people explode when you shoot them with big guns.
