Fun thread. ADK (aka Alpha Denshi) and Arika have made some excellent, underappreciated fighting games.
- ADK got a bad rap with World Heroes, which started as a pretty shameless Street Fighter II clone. But it gained a stronger and stronger identity with each iteration, culminating in World Heroes Perfect, a really great fighting game with an awesome cast and tons of personality.
Trivia: World Heroes Perfect is the first and (I am pretty sure) only 2D fighting game with head tracking, i.e. when one character jumps, the character on the ground looks up at him.
- ADK also did a game called Ninja Master's, a bit like Samurai Shodown but with a darker vibe. Some great, memorable character designs and a cool combo system where you had different moves with and without your weapon.
- As for Arika, I always felt Street Fighter EX + Alpha was grossly underappreciated. There was a ton of stigma around the idea of a 3D Street Fighter, but EX + Alpha played like 2D, had some great animation and feel, did radical and cool things with the classic characters, and introduced new character designs that were straight-up better than what Capcom was doing (e.g. Skullomania, Darun Mister, and Cracker Jack).
