I think mine was a Goomba, but it very well could have been a duck from Duck Hunt. What was your first videogame kill/destroy?
The first helicopter flying terrorist in Cobra Command, in a huge seated arcade machine at an odd smelling Chucky Cheese during my 4th birthday. I was so tiny that my brother had to use the other flight stick for me since I couldn't reach it.
Then came the 1-1 Goomba.
