- Shadow of the Ninja
- Kabuki Quantum Fighter
- Vice: Project Doom
- Power Blade
- Power Blade 2
...because I love that Super Action aesthetic my real list would probably look more like:
Two player co-op. Immediate pick-up-and-play gameplay, and enough power-ups to prevent boredom.
Mega Man 2
The height of the series, and the US difficulty settings makes it more accessible. Also, solid enemy and level designs, and no superfluous charge-shot or slide.
River City Ransom
An excellent example of a game being localized for the better without losing its charm. Double-tap to dash, an assortment of moves, and stat upgrades, items & currency all make this one stand above the rest of the beat em up genre.
What I consider to be the epitome of Tetris, not surpassed prior or since. Two-player competitive and co-op options make it shine.
Absurdly addictive. Only lacking a 2-player feature.
Shadow of the Ninja
Even without co-op, this would've surpassed the other ninja titles on the system for gameplay alone.
Another title improved by its localization. Of the Super Action titles in my first list, this one pulls everything off the best.
This one almost didn't make the list, because of its breaking of the "have a computer-controlled sidekick, but no co-op option" rule, but the game still stands despite it. Fantastic character design and a blast to play.
