There's a fair few franchises I'd love to see brought back in a serious way. Full HD graphics, power and storage of consoles to hold bigger, more expansive universes and stories. Hell yeah!

- Pandemonium this was a pair of brilliant platforming games (would be great on the handheld markets these days)
- Gex enter the Gecko
- Colony Wars (oh for the love of god how much I'd like to see this! Red Sun at the time was one of the most expansive space opera's out there in game form, there was lots to it but the limitations of technology prevented a lot more being done)
- Jaeger (a little known space combat sim for Xbox deserves a sequel)
- Phantom Crash (mech combat arcade simulation mixed with Gran Turismo, mixed with a Jet Set Radio style graphical feel. It had plenty of funk on xbox again, was a ps2 release which essentally became too western and lost the name of the franchise, still pretty much the same idea)
- Bully 2
- Battlefront 3

The above would be a start but there's plenty more where it came from
