point n' click PC adveture games sounds like the most logical one.
I would have said MAME but the "Not of Japanese origin" pretty much ended that.
When I first read the story I thought it could have been one of these:
- Final Fantasy VII on the VC since FFVII came out in 1997 it would make it close to 10 years old. Thou the built-in memeory wouldn't really suport it, maybe by then Nintendo would alow you to run games off of a USB or SD card.
- SNK NEO-GEO, It came out in 1990 and its a retro gamers dream. And SNK has mentioned that they were in talks with Nintendo about suporting the VC
- MAME, Arcade games would be a pretty safe bet, I mean MS has arcade games.
- Apple Pippin games, Yes all 20(give or take) games for it.
- Classic PC FPS (Doom, Quake, Wolfenstein, Duke Nukem)
