What do you guys remember about Sunset Riders, a 1991 shoot-'em-up arcade game released by Konami that is set in the American Old West?
You and three of your friends play as one of four cowboys per player: Steve, Billy, Bob and Cormano. Only the arcade version allowed up to 4 players per game; all home versions (none available in Japan, oddly) limited multiplayer ability to 2 players. Furthermore, the Sega Genesis port removed Steve and Billy as playable characters.
Both the Super NES and Genesis versions were heavily censored and were thus stripped of all references to American Indians (the Super NES port removed all references to women as well; the Super NES port changes the American Indian boss's name from Chief Scalpem to Chief Wigwam). Those censors alone would've been ignored in the Japanese Super Famicom and Mega Drive ports if they existed there, but didn't.
I also think that SR could've seen an 8-bit NES release but, I would think it not to sell well due to the fact that the NES is old technology; it would of course remove all the voices, in addition to the Genesis version's heavy stripping down.
