Heh, I remember there were several different Carmen Sandiego games. Where in the USA, Where in the World, Where in Time. I remember playing Where in the World is Carmen Sandiego on my 4 color CGA.

My first computer games were probably the shareware ones that came on 5.25" disks with computer magazines back in the 80s. I remember Kingdom of Kroz and Dr. Seeptite pretty well.

I remember when Doom came out, it was so amazing. I still play Doom, using an OpenGL port, jDoom.
