Look, Fallout(s) 1 and 2 (BROTHERHOOD OF STEEL NEVER HAPPENED SHUT UP) are almost completely different games. A lot of people preferred the old turn based combat that the first games had, and a lot of people who considered themselves hardcore raged about V.A.T.S. (Something that you never have to use if you don't want to?). Also, a lot of people, including me, found the game only challenging for the first few levels, when all you had was your shit pistol and BB gun, but once you get to level four or five, the difficulty, as Yahtzee said, vanishes. At that level you have so much health (or stimpaks) and ammunition, that you only need to visit your local shopkeep once a week if you use your ammunition carefully. Hell, this guy [http://www.escapistmagazine.com/profiles/view/Snotnarok] is even playing through the game without visiting any towns, along with using difficulty mods to increase the toughness of the game. Now, don't get me wrong, I personally adore the game and it's atmosphere, but many fans of the original series dislike the storytelling of Fallout 3, and adored the storytelling in the first two (NOT THREE) games, as well as the campy humour that wasn't very prominent in Fallout 3, but that is just my opinion. Also, the people above me said, it's a great game with some problems, for example, everything I just said about it up there, and the fact that one time (Now this is the PC version, children) I was playing the game for two hours, and it crashed six times! That is three crashes per hour. The game is inexcusably buggy, and apparently Bethesda thinks that patching their games frequently to fix bugs is an ass-backward idea.
Oh, but it's still good, pick it up if you don't have it.
