Shamus. It was a little guy going through a maze getting keys to unlock doors. The goal was to solve the mystery of something. Can't remember. It was for the Atari 800 with a floppy drive.
My earliest "game" was Logo, playing with turtle graphics. Later on: Lode Runner, Test Drive, Xenon, Ultima and FF series, etc., and some Chinese and Japanese games that probably don't have appropriate English translations. I started from cassette tapes and 5.25" floppies; first machine was X-80 (8-bit). I appreciate both old games and new games.
