If they were to retouch things up, improve visuals some ...
For PSN, I'd want either MGS1, Vagrant Story, or Parasite Eve.
For VC, I'd want either Goldeneye 007, one of the wrestling games, or Perfect Dark.
Edit: Or or ... I always loved the two adventure games for Genesis, Out of this World and Flashback. I'd love to see them on VC. Or NiGHTS, Panzer Dragoon, Fighting Vipers, Virtual On, Virtua Cop 1/2 from Sega Saturn.
