If you've played Baldur's Gate: Dark Alliance, you'll quickly notice that Brotherhood of Steel uses the same engine. The menus and all the graphics are different, but the feel and the mechanics of the two games are almost identical. The PS2 and Xbox versions look similar at a glance, though the Xbox version is a little cleaner and sharper. In gameplay terms, the main differences between Fallout and Baldur's Gate is that Fallout features a lot more ranged weapons than Baldur's Gate does (though there are plenty of melee weapons available, too). Also, while there are some special abilities in Fallout, obviously there aren't any magic spells.
