One of the most ahead of its time Fighting Game crossovers because it features Ryu, Chun-Li and Vega/M. Bison from Street Fighter, Mario and Bowser from Super Mario, Sonic the Hedgehog from Himself, Leonardo from TMNT, Haggar from Final Fight, Andy, Mai and Laurence from Garou Densetsu/Fatal Fury and Goku from Dragon Ball and the idea itself is a good one.
However, the playable scheme and the learning curve leave a lot to be desired for being half-unplayable until you have to make complex commands how to do a specific direction with 2 cuff and kick buttons at the same time to make a special move to win and unfair because the CPU spams the same special moves all the time and then everything so you lose a round, and this problem is not only in this game but in all pirate fighting games developed by Cony Soft for the Famicom.
