I feel like I'm the only one that even remembers that game, let alone liked it, but it was a pretty fun 3D platformer that I'd like to see get a second chance at fame...
Oh, and Parasite Eve I & II, of course. I wouldn't mind seeing Parasite Eve II redone in full 3D, though I'd imagine many would see that as heresy.
Come to think of it, after playing the recent updates of Day of The Tentacle and Gabriel Knight: Sins of The Fathers, I'd love to see most of the old Lucas Arts -- Full Throttle, especially, I've heard rumors an update of it is the works -- and Sierra adventure games get redone. Trilobyte's The 7th Guest, too, though I think I'd leave The 11th Hour dead and buried.
Sadly I don't think redoing the FMV games would work, though. The cheese of Phantasmagoria and Gabriel Knight: The Beast Within were so much a product of their time.
