I played Snake Eater at E3, very freakin crowded. Im not a big fan of MGS, but they passed out the OST encased in a record album cover, it was pretty sweet.
I find the Metal Gear games alot better than the Splinter Cell ones...though Splinter Cell is still good, but they seem to be just pumping them out instead of trying to add more to the story and just giving the same tired action over and over again.
story like in mgs2? as in more cut scenes than one those segacd games from back in the day. splinter cells better because you actually GET to play the game, not just sit there watching the screen.
