Playing Snake and Frogger on DOS.. Probably around 1990 when I was 3.. Then later we got Jungle Jane, and that was a friggin EPIC game! That was when we got a real color screen, so maybe around 1992 ish.. It was at least a few years before we got Win95..
I think we had commander keen before we got the win95 machine, but I really don't remember..
Oh man.. that computer was SICK! It had over a GIGABYTE HD!! I remember my dad saying "Just install whatever games you want on it.. It will probably never get filled up."
Then, on win95.. Guess what I played : ) DOOM!!! : ) 8 years old and playing Doom : ) Of course, with godmode on and hardest difficulty, running around with the chainsaw : )
