i was born in 1984 and the first time i had used computer was in 1996 so playing a PC game in 80's is out of question!!!
Wow...In the early 80's it was all Atari for me! Pong, Pac-Man, Frogger, Space Invaders...Then in the late 90's I was introduced to Tetris and that is my all time favorite game!!! I have it on my computer, iPod, and phone!!! When you need a break, it is a great way to zone out!!!
My favorites were all in Nintendo console. Games like Super Mario, TMNT 3, Pacman, Tetris, Jackal, Tank etc.. were my favorites. I still play some of them in PC using NES.
Atari, in my opinion. It had cool joysticks and basic games. But it was great. Nintendo was cool as well - I remember some monkey game, tennis, kung fu, etc.
another fun one for the C64, Dig-Dug then for Arcade game it had to have been Galaga and actually it's still my friend's favorite, some 2 decades later!!!
I used to work with the guy who developed Wizardry and Qbert - well worked with, in the sense that he was an attorney and I worked in the mailroom . He's an intellectual property attorney here in Tampa. He's a nice guy, too, always liked talking about Wizardry especially!
