From Capcom Database Wiki

Capcom vs. SNK 2 (subtitled: Mark of the Millennium) is a sequel to the fighting game Capcom vs. SNK, released in 2001. It is the sixth game in the Versus series. Like the original, it featured art by Kinu Nishimura and character art by Shinkiro. The game is a popular favorite among fans. Capcom vs. SNK 2 EO is the same game, but with minor changes in gameplay and the inclusion of an EO ("Extreme Offence") system that allows the player to perform specific attacks simply by moving the right analog stick in a certain direction. Many players felt that the EO version wasn't challenging enough, since special moves could now be performed so easily.
