1987 - Blast Force, Commodore 64
Probably my first completed game ever (at least if you don't count the previous questionable attempts in Basic :) Coded straight in a machine code monitor that were located on a cartridge belonging to my cousin. I didn't even know what an assembler was yet. At this time it was very difficult to find books or articles about programming, especially for a boy living in Sweden.
