Oblivion, but no morrowind? What you say!! Morrowind was one of the first games to employ a genuine composer and orchestra, and had an immersive, genuinely brilliant soundtrack. It never trampled over the gameplay, always fitted the game, but also sounded passable as a neo-classical piece separate of the game. If sodding ZELDA can be on this list, there's a good case to be made for Morrowind's place. EDIT - and Final Fantasy is taking the lead, closely followed by Halo. The poll may as well have just been (Halo), (Half-Life), (Final Fantasy). They're where the money is, really, and we all know it
