While doing some searching on Google for legitimate work reasons, I stumbled upon Classic '80's Games. The Google link caught my eye.
Being the avid game player I am, I bookmarked it and moved along to the legitimate work I was doing.
Though not all the games on this page are from the 80's (Pong), most are, and many will make you smile.
Games like Duck Hunt, Pacman, Frogger, and Space Invaders are just a few.
Take a look!
