Yes, the NES/SNES era was flooded with shoot-em-up platformers,and the Super Star Wars/Super ESB/Super ROTJ was of this type. But other stuff was around. I've always found this type of game very hard, and that is why I never did good in this era. Video games seem to go through fad games, and they get endless clones. In the Atari 2600, it was Pac-Man/Defender. Then in NES/SNES it was platformers, later fighting games.
