Another set of games that I thought was really cool was the PC versions of arcade games. There was a vector graphics rendering engine available in the 80's and games like "Tempest" and "Asteroids" ran on it. There were literally dozens if not hundreds of other popular games too, but those are just the ones I remember the best. I probably might have those around here somewhere too, so I think I'll go have look for them. This little walk down "memory lane" has made me want to revisit some of these old fun things.
