If Metal Slug wasn't enough...
SNK Playmore has already supported the Wii with the Metal Slug Anthology release, chronicling seven different Metal Slugs. Recently, Nintendo's Japanese website has quietly snuck in the Neo Geo AES as a new addition to the Virtual Console lineup! Scheduled for a 2007 release (along with the MSX home computer, home to Metal Gear), the Neo Geo adds a whole decade of games to an already strong download lineup. I pray Nintendo is smart enough to bring this capability Stateside.
Now WHERE'S MY KING OF FIGHTERS? Hell, screw that, WHERE'S MY BLAZING STAR?!?!??
