You know, it goes both ways. I always get a chuckle at the people that defend MGS's story as somehow being above the critics' comprehension and that we somehow miss the supposedly deep undertones of the plot. I just can't even believe people would be so blind to the fact that MGS is just piss poor storytelling. All the "you're too stupid!" comments just boggles the mind. IMO most of the obscene smugness and outright elitism is coming from the people with snake avatars and codec frequency tattoos.
And yeah, I have no doubt that unless they completely (and I mean COMPLETELY) retool the MGS storyline it'd make for an outright horrible movie. Attack of the Clones level bad.
but do you honestly not see how MGS4's story is more than just snake versus the bad guys? i think it's kinda silly when people make claims thrashing all over MGS games' story when they only seem to consider what's on the surface--they take it too literally.
MGS4 is more fresh on my mind so i'll stick with that without going into the other games. kojima likes metaphors though, and i don't think people are used to having strong metaphors in games yet. when you take MGS4 by face value, it's definitely ridiculous. we could list plenty of ridiculous elements to MGS4, but i want to mention one in particular. i'd listen on 1up yours as shawn would argue against the logistics and viability of a future with PMCs like in MGS4; yeah, PMCs can't really exist like that. but i don't think that's the point. i think PMC soldiers were more a metaphor.
it seemed pretty obvious to me at the time and i'm sure i could draw specific examples if i went and played through it again, but i saw a lot of metaphors to the current gaming industry/community. the PMC soldiers are a metaphor for the forum soldiers you see on any given gaming forum. PMC soldiers fight endless proxy battles for their company much like forum soldiers endlessly argue for their company. several times, i saw kojima represented in snake. snake is upset with the current war industry in the game--kojima seems upset over the games industry. snake mentions that "war has changed" and that war is no longer about ideologies, profit, ethnicity, or resources (these are what all wars typically result from). you can compare that to the game industry and how it's also changed. while you could argue it's just people being lost in nostalgia, it's not uncommon for people to think the game industry has changed--going from being about delivering deep gameplay experiences to now being more about the profits and metacritic scores. snake is old and tired. kojima seems to be tired of doing MGS games.
and some people will try to break this metaphor by bringing up examples where it doesn't necessarily work on the same level in every area--but that's not how metaphors work. metaphors don't have to obey strict rules or be 100% consistent throughout. metaphors can adapt, change, and morph. metaphors can take on multiple meanings. and these aren't really high-level concepts or anything... metaphors are pretty basic in literature. i just don't think people are used to seeing them in games.
i don't think MGS4 is purely a metaphor--i don't think kojima is just making a statement or whatever. he's also interested in delivering an entertaining story, and i think he succeeds there. if it were translated into a movie, i think there'd have to be a lot of retooling, but not necessarily with the story--they'd have to retool the delivery. i don't necessarily think MGS games are "genius" but they're undoubtedly up near the top when it comes to video game stories. they're some of the only games that even make an attempt to be more than just good guy vs bad guys.
