Xenosaga 3-6 (original versions)
Baten Kaitos DS
Chrono Break (you know it was in development)
Dead or Alive: Code Cronus
Dinosaur Planet
Cry On (even if the concept sounded silly)
Starfox 2 and Super Mario FX (even though they'd probably both suck... just out of curiosity, really)
Mother 64
Raven Blade (again, probably would have sucked... just want to play out of curiosity, to see how Retro would have handled this kind of setting)
Fire Emblem 64
Super Mario 64 2
Conker 64 (original version, just to see how much it contrasts with the final product)
Dead Phoenix
Super Mario 128
Persona PSP (the original announcement... I assumed it was going to be an original game)
Monster Hunter 3 (PS3)
Skies of Arcadia 2 - GameCube
Final Fantasy VII, VIII, IX remakes - PS2
Never heard of these, I'd love to hear more. Got any more info?
