I've been playing video games for most of my life...about 25 years of solid gameplay now. Though I prefer Zelda and Mario (have played through every single one of each of those, from the beginning), I also like DragonBallZ games, Tony Hawk, Soul Caliber, Sims, SimCity, and tons of other games. I am also guilty of computer games and have really enjoyed, in the past, the old school King's Quest games.
And to tell you how big of a nerd I am...I have a program installed on my old laptop that allows M. to play EVERY NES game EVER created, no internet required, including a bunch of black market offshoots (like, Mario collects needles instead of coins, etc) and I LOVE it. I've had it for over ten years.
A few really old fun ones from NES...besides Mario and Zelda...Excitebike, Gyromite, Snoopy's Olympics (??), Mickey Mousecapades, and Goonies II.
I also freak out on video games music and Koji Kondo is my absolute favorite composer, despite being a classically trained musician.
