Man i really liked death match mode in world heroes 2, u gain the energy the opponent loses.
I Never understood why it never picked up, i found that awesome.
I also like in battle arena toshinden that you could win by kicking people over the edge, dont understand why every hated the game, but maybe it wasnt so good my memory is Not the best.
But for me the favorite fighting games are still Street Fighter 2 snes, fatal fury and samurai showdown
