Final Fantasy X (it played like a movie...very linear, felt like a movie...lovely story)
The Legend of Zelda: The Ocarina of Time (this was where the game series took a very epic and cinematic turn...plus everything after seems too complicated to be movie material)
Metal Gear Solid (I don't care which game it follows or if it's an original story line...but these games have wonderful writers and they need to be involved in a movie adaptation...these games ar also heavily cinematic...skip all the cut scenes and you lose like...60% of the game)
^ Wow thank you i cant believe i didnt think of those, well ocarana of time would be a bit weird, the whole going back in time and forward, would be a very limited audience to understand wtf is going on lol! id want it to be a cgi though, instead of real actors, unlike metal gear solid, have kurt russle play snake!
I could imagine a live action Ocarina of Time with movies like LOTR, Narnia and Eragon out these days. it'd fit in really well with great casting.
Of all of them I'd like to see FFX. It really had a powerful, poignant story with a lot of depth to it. Religion vs. technology...abandoning old practices...forbidden love...political responsiblity...it was rife with soooo much for a movie.
But come on, have you even played Final Fantasy VIII. The cut scenes themselves are a movie. Balamb Garden, Selphie, Quistis, Rinoa, Squall, Zell and Irvine all animated! It would be a dream.
Also, Karin Kanzuki from Street Fighter Alpha or Zero 3, is the only reason why there should be a film for the Game. Within the film she will finally get the chance to beat up Sakura. Everyone knows that Karin is stronger!
I just watched FFVII Advent Children yesterday and I was amazed, the world need a Movie make of FFVIII, the best game in the world.!
