I just watched the video, I can't wait to get this game, MGS is one of my favourite games of all time.
MGS2 was not that bad, the mechanics were great, it's just that the story wasn't. That's why combining the story of MGS one with the graphics and gameplay of MGS2 will be great. And I didn't find Snake's "absence" in MGS2 that bad either... It's like saying Metal Slug 3 is bad because Solid Snake is not in there...
I passed almost all the VR missions in Substance, but didn't play the main game as I already finished the regular MGS2.
About the video, I'm pissed it's only cinematics (although they use the same game engine), instead of some controllable action. And by the way, why the hell do EVERYBODY and their mamas have the need to use "bullet time" in any action sequence since Matrix?
