The president of SNK Playmore USA recently announced that the North American Wii Virtual Console will start to receive Neo-Geo games very soon, at an average of "around two a month." SNES VC games cost 800 Wii points ($8 US), and Neo-Geo games will cost "a little above the SNES point."
SNK has been a popular video game company for well over a decade, getting their start by developing video games exclusively for arcades and eventually creating a home version of their arcade hardware with the SNK Neo-Geo. They have created several popular series over the years, including King of Fighters, Metal Slug, Samurai Shodown, and many more. As Neo-Geo systems are outrageously rare and expensive, this is an excellent opportunity for the both enthusiastic and curious fan who wish to enjoy Neo-Geo games through legal means without spending a great deal of money.
