The Commodore 64 was really neat for those simple BASIC text input parsing games, I did do a text adventure a few times and that was great fun. Even went as far that I had a song playing in the intro and a sprite moving. Wow! Now I am still doing some stuff on it and maybe I'll fulfil that dream of creating a real sideway scrolling platform game for it.
Though I only realised yesterday that the CU Amiga 016 cover disk actually contained a copy for Pro Tracker 2 as well (where I started later with FastTracker II on the PC and I was totally hooked since then to making music), I did do a lot of graphics with it and made some bad games with SEUCK. But I never programmed anything with it, I guess the lack of default programming environment, preferably one you booted straight into was the cause of that.
