Contra is one of my most favorite games on the NES.
It's a very addicting game which I have played over and over when I was still in grade school.
I can never forget this game.
Another favorite of mine is
Battle City.
This game took up a lot of my time along with my uncles.
Chrono Trigger is probably one of the finest turn-based RPGs ever made.
This was my favorite game on the Super Nintendo.
Legend of Zelda: Ocarina of Time - for me, this is the most memorable Zelda game and my favorite of all time.
Super Smash Bros. - I had fun with this game when me and my friends in high school had to finish a project and we had to have an overnight session at one of our friend's house. We didn't finish the project, but we had a blast playing this game. Haha!
