Did any of you play a game as a child, maybe just at an older friends or cousins place, and not realise what the game was until MUCH later?

I've only just realised that I HAVE in fact played Contra. I've always thought Contra was some bad-ass old school game that everyone except me had played. Then I bump into some screenshots randomly and I was returned to a world of youthful innocence. xD

Man I love Contra.

I had a similar thing happen with Dr. Mario and Keen but for those it didn't take me as long to notice.
