Remember, I was assembled myself in 1979
A few of the games I like M.U.L.E. & Archon (C64). I was quite a bit older than 4 when I ran into M.U.L.E.
Atari (don't know the exact type
) Pitfall. Two levels, and I played a perfect first level. Quite an accomplishment, as you cannot save your game ever.
Early PC: of course chess (Psion). And a few other games, even though I have a hard time remembering exactly what they were. They were good enough excuses to get out of bed at 4AM though.
Games I could spend hours on, so they must have appealed to my perfectionistic side.
Amiga 500: MadTV. And a few other games, but sometimes it is hard to know if it were originally PC games or not. MadTV is also available on PC too. Strange enough, I have not run in a funnier management game since that time - and it was released in the very early nineties!
