Life Force on the NES. I really didn't get to play many video games until I got my NES X-mas 1987. I remember my cousin returning a Gradius rental on the NES before I got my system, but I never got to see it or play it. Anyways, first time playing Life Force was when my mom rented it for my friend Terry and I. He had a sub to Nintendo Power and knew about the Konami code working and we went right through it 2 player.
The first Shootemup I owned was Abadox. It was OK actually. I don't have my copy due to the Thomas Floyd Randall incident of 96.
Me: "Hey Floyd, where are my NES games I let you borrow???"
Floyd: "Man, I, I, I lost em man."
Me: What in the hell do you mean you lost them? Those were like 15 games dude!".
I forgave him as he was the Nintendo King of our town. This guy could beat any game you throw at him.
