Games Radar's biggest beef with Volume 2 is the lack of online play (the Japanese version offered it, but cost more). Also, the absence of any sort of bonus content feels like a glaring omission. Considering that this is a collection of classics, some development artwork or historical background would've been nice addition for Fatal Fury fans.
Still, they can't whine too loudly, considering that Fatal Fury: Battle Archives Vol. 2 gives you three solid fighting games for roughly the price of a couple fast food lunches.
