We got curious about this when some readers described system-based organization of VC games in a recent WWU: From which system do most of your Virtual Console games originate? We would guess that the NES would dominate most collections, due to the lower price of the games. Similarly, we doubt there are many Nintendo 64-heavy collections, due both to the increased price and reduced selection.
But, really, we have no idea. Maybe your Wii Menus are full of surprises.
