I'm not a freak fan but, it should be seven.
It really should be.
you know, it would be nice if they put that energy into something else... something new. A follow up to a franchise that they left behind, despite how well it was received. Like say, oh... Einhander II.
I am so not interested in this. I'd prefer an HD Chrono Cross rerelease. That'd be swell.
Aside from graphics, translation and audio quality, FF7 still stands the test of time. The game is extremely long with tons of side quests, secrets, character customization, etc. Combat is still fast-paced and fun, between limit breaks, lots of magic/summons and command combinations. A next-gen remake/retranslation of the game would easily stand on its own.
Same with Spiderman movies. I don't think a remake is possible.
What they said... +"Rad Racer" to The Coop's comment.
