Summary
Whoever thought of this game was a lunatic
The Good
The main character was sort of interesting, despite his weird sideburns.
The Bad
Aside from the multitude of minor problems, there is one, *main* issue.
WHO THOUGHT OF BASING A GENESIS GAME ON ROCK, PAPER, SCISSORS? It is the worst translation ever. Rock, Pa... etc. is a game of either chance or advanced psychological calculations. The computer thoroughly rules out the second possibility, so it's off to infuriation land (or the Enchanted Castle) to develop a "knack" for defeating your enemies.
The Bottom Line
Don't play it, don't associate with it. If I were you, I'd instead invest in something safe, like tetris. You are warned.
