but seriously, not know about Duke Nukem is only slightly more unbelievable then not knowing about Super Mario.
Super Mario? nope, don't think I've heard of Mario....
JK I believe the next "slightly more unbelievable" thing would after Mario would be Legend of Zelda, or Duck Hunt...
Was Duke Nukem more of a PC game when it first came out or was it associated with a game console like Nintendo, Sega...ect ?
