What games have you played that you thought could do with a fresh update or sequel? And what would you like to see in this sequel? (If anyone says Mario Party I ****ing swear to God

)
I'd love to see a new version of the F-Zero games. It's fun, challenging but simple enough to pick up, inventive, really ****ing cool and has quite a lot of untapped potential. Each character (there's usually 30 in each game) has their own story and considering they've done a story mode before (albeit short and corny) it'd be cool to see them do it again, but deeper and better.
Plus considering graphics are so much better since their last release (2003) I'd love to see how they'd do the vehicles, new insane courses and the generally awesome futuristic/comic book style applied.
And of course, because Captain Falcon.
