Rambo
It’s Ikari Warriors only worse and with terrible gameplay and overall awfulness.
Rampage
I would argue this is the best Godzilla game ever made. Well, the arcade version is. This is still pretty solid.
Rampart
Well, the combination of a turret shooter and a land-management Tetris game is surprisingly addictive.
Shadow of the Beast
Credit where it's due, the sprite art in this game is great. The game, though, is a garbage fire.
Shinobi
Well this is basically a slower, clunkier, ninja-themed Contra. I am not impressed at all.
