Metal Gear Solid 2: Substance
MGS2S is an expansion. Or enhancement. Or something. Metal Gear Solid 2: Sons of Liberty was released on PS2 a while back, and this is a 'gold edition' style release: 5 new "Snake Tales" (mini-stories), 200 "VR missions" (tests of skill etc) and 100 "alternative missions" (same as old ones with slightly different placements or objectives) all in addition to the existing game. While the whole title makes an attractive proposition to XBox owners (whom have never had a Metal Gear title), I'm not sure that a few extra missions warrants spending full price on a new game for PS2 owners who already have the previous release. We shall see.
