In fact, that's the real root of the problem with King of Fighters: The Orochi Saga. This series barely evolves at all, so this is a grouping of five versions of essentially the same game. Thus, it isn't really for anyone but the super fans. Even for a casual SNK fan, it's a bit much. And when SNK seems to release a new collection of its many old titles every week, most with at least one version of King of Fighters or its ilk on it along with a more diverse set of classics (Final Fight, Art of Fighting, Fatal Fury, World Heroes, Samurai Shodown), it's even more redundant. It may have an inviting price, but so do other SNK collections, so be sure you check them out as well to make sure you're buying the one that's best for you.
