Yea,its true,Riot Zone is infact a sequal to Riot City.Riot City was a failed attempt to do a Final Fight clone on Segas System 16 arcade hardware.For all your complaints about Riot Zone,I find I like it alot actually.I like it alot more then the sequals to Final Fight,and the extremely crappy clones made by Jaleco on the Snes.Lets face it,a game like Final Fight would have required a tad more ram space then the Super-cd technoligy had,for animation and all,and really they did pretty well with what they had to work with on Riot Zone.The only other "GOOD" beat'em up is the remake of Double Dragon 2,which has smaller sprites and was a "upgrade" fo the arcade game,which infact felt more like Double Dragon 2 on the Nes then it felt like the arcade game.
I think if the arcade card had come into play,you would have seen better,perhaps even CPS1 quality beat'em ups like Final Fight,but alas it didnt happen,and life goes on.Lets face it though,the Snes Final Fight sucks too,its stripped down and raped of 2 player action and levels,and girl hooker chicks to beat up,and pretty much all the Final Fight clones on Snes had the old letterbox screen size to them like the 1 on 1 fighters did.
I think this is the only area the Genesis and Sega Cd had our favorite system over by the balls.The Sega Cd had a wonderful Final Fight port uncensored,and the Streets of Rage games are wonderful,as is the Punisher port for the Genesis.Oh yea and near arcade perfect ports of Double Dragon 1 and 2 for the Genesis and Mega Drive respectivly.
The only Snes beat'em up I will always love is Super Double Dragon.It had tons of moves,power up moves,weapons,trow moves and all.Its stages were all very cool.Its graphics and sound were top notch.Its a TRUE classic for a home system.
