It's kind of interesting to see franchises that blossomed and/or thrived on the NES and SNES move on to other consoles. Not every developer is trying to snub Nintendo; sometimes the hardware diversity and the nature of the market dictate where a franchise must go. Yet it doesn't hurt any less when we hear about a sure-to-be awesome game announced for systems other than our own.
Metal Gear Solid 4 follows the ongoing chronicles of Solid Snake. The Metal Gear Solid games present their story in a similar way as the television show Lost: in order to fully comprehend what's going on, you can't afford to miss an episode. And as I never got the chance to play Metal Gear Solid 3, I didn't want to be spoiled by reading about Metal Gear Solid 4. Thus, I can't provide details about its plot. What I can say is that the previous MGS titles blurred the line between games and cinema like no other game before it, and just imagining this experience in HD makes Solid Snake's latest adventure all the more drool-worthy (to put it elegantly).
