...But in the event that doesn't count... Hm... I guess the Wii, since it can play Gamecube games, I have some other good classics on there for the Wii virtual console, and Nintendo has some pretty good franchises going for it.
Failing that, the PS2 would be a great choice as well. Especially considering that some of my favourites are on there too (Ace Combat, mostly) and there's backwards compatibility with PS1 games.
