this genre being one of my favorites, i have tried to track down every single game. since no website seems to have a complete listing or mish-mashes genres into a mess of search - i want to create one. anyone is asked simply to state the name of the game and the system it was created on. i must ask not to name any kind of "beat 'em up" that isn't a brawler (ie. final fight), like versus fighters (ie, mortal kombat, tekken). additionally, try not to stick any action/platforms titles in, even if they consist of punching/etc. multiple foes.
to start this off, i introduce the most obvious:
final fight - arcade
final fight - snes/sfc
final fight 2 - snes/sfc
final fight 3 aka fight fight tough - snes/sfc
final fight guy - snes/sfc
final fight one - gba
mighty final fight - nes/famicom
final fight cd - segacd/megacd
streets of rage - arcade
streets of rage aka bare knuckle - sega genesis/sega megadrive
streets of rage 2 aka bare knuckle 2 - sega genesis/sega megadrive
streets of rage 3 aka bare knuckle 3 - sega genesis/sega megadrive
streets of rage - gamegear
streets of rage 2 - gamegear
streets of rage - sega master system
streets of rage 2 - sega master system
streets of rage - sega cd
sega ages: bare knuckle - ps2 (unverified)
rival turf aka rushing beat - snes/sfc
brawl brothers aka rushing beat beat ran fukesei toshi - snes/sfc
the peacekeepers aka rushing beat shura - snes/sfc
