I played Mortal Kombat 2+ when i was 8, Doom and Wolfenstein 3d A little bit later, and Duke Nukem.. I actually played Duke Nukem on one of those early Virtual Reality Helmets, whole new dimension to violence, wonder why that didnt catch on... I was 11 or 12 i think
Looking back, i really never thought of any of those games to be particularly inapropriate for me, the vilence hasnt stirred up emotions at all. Although with todays graphics effects things might be different if i was a kid again? Hmm
