Even though I never owned it it turns out my father had a copy of X-Man by Gamex stashed away, he told me he "got rid of it" after we donated our old Atari.
I don't believe him though.
I remember being really into submarines back when I was a little kid so my parents picked up a copy of Polaris for me for Christmas I played the crap out of that game, I also had Bermuda Triangle, and Quick Step. At least one of those games was fun
