If my memory serves me right, I bought Ring King for the NES 32 years ago tonight at Kmart.
I could've bought Mike Tyson's Punch-Out for several dollars less than what Ring King cost. But I honestly thought that MTPO would suck because the opponents were twice as tall as Little Mac.
A few weeks later my brother bought MTPO and to my surprise, I liked it better than Ring King and after seeing my brother play it, I bought it.
But Ring King was still a great NES game and it is more realistic than MTPO.
