Sometimes IGN(matt/peer) have said they rate games against the standards set by a game's peers, aka the console's current library. MGS1 on PSX was rated based on what came before it, at the time it was released. Our MGSTTS, graphically in-game, has to stand up against the likes of say, Metroid Prime (which has a deliciously smooth framerate). On the control side, effective control schemes like those of Zelda:WW and Eternal Darkness also pre-date Twin Snakes, which could reasonably justify a dissappointment in the lack of analog character movement in Snake. Then there's the phenomemon of Snake's combat movements seeming vastly simplified compared to the cool stuff in the cutscenes -- I'm not sure how to explain that other than Konami is happy with that, just as players were happy with MGS2's boss fights. Then I remind myself MGS2 originally came out for PS2, and came out a while ago, where it was rated against the peers of its own time.
mouse, isn't the core material of Twins Snakes the ["modern" or "not that modern anymore"] gameplay mechanics of MGS2 that's applied to MGS1's old level design, though? So help me out: what should Twin Snakes be rated against?
