1. A Dreamcast 360 remote (hell yeah [not gonna happen...])
2. No load times (quite impossible however) << but still a 3-4 second load screen to show the area names.
3. Uncompressed textures would be cool.
4. Japanese and English voices (original Yuan voice too)
5. Some type of classic mode if updated graphics are included.
6. Working Shenmue 2 video filters, working S2 music.
7. Original Shenmue music, not diffrent music like what happened with Crazy Taxi (albeit its music was licensed)
8. Proper Yu Suzuki logo.
9. Physical disc would be cool, however my next gens are hacked, I could make my own.
10. 3.55OFW Keys for PS3 version
11. Shenmue Passport for XBLA
Most importantly
A tribute to Shenmuedojo and Shenmuemaster for keeping the community alive!
I can think of so many others.
