> You're not wrong. DD1/2 and Rygar are among the games where the NES port played better than the arcade.
Double Dragon just had the hardware slow-down issue. DD2 didn't have that, and there were more and cooler moves (because ultimately the elbow move, lackluster though it was, in DD was the only decent move). I don't recall anything being wrong with it.
Still, Double Dragon was fun enough. I was in high school when it was released, and I had not been keeping up with video games, so it was my first experience with the type.
((I mean, I was imagining translucent images in a transparent screen (the windshield of my Matchbox '70 crimson red, white-top Challenger) at perhaps nine or ten - this was before Star Trek II, even - so arcade games only somewhat got my attention. I wanted 3D back then. Ironic my current sentiments about that, and 2D games, respectively.))
Rygar was just a crappy game. Black Tiger was the mature version of the period, and rightly so, it was a Capcom game.
