I call BS! Only 24%.
I got the following right: 8, 9, 10, 23, 24, 32, 34, 35, 39, 45, 48, & 49. The rest I've never heard. For my excuse, I'm going to appeal to the fact that I wasn't allowed to own any mainstream systems until 1997.
I'd like to see the answer key, because I wonder how many of these games I've actually played. Hell, I've never even heard of "Psycho Fox."
