I think SNK decided to put characters in this game that always play second fiddle in other games... I'm glad Genjyuro, Demitri, Zero, Earthquake, Choi, and some other characters were put in the game... Mars People was one of the best additions imo, since they beefed him up in NGBC, and he was a good counter to Dhalsim...
It would've been great to see Donovan, Setsuna, Zazzie (FHD), Rick Strowd, Akira (Project Justice), Chairperson (Project Justice), Cyber Akuma, and Saizo (Breakers Revenge) in this game... The graphics were gritty and they used lighting tricks for a 2d game...
