PC What was the first game your bought

I'm in my early forties so the first experience I had gaming was on the Coleco Intellivision, a console that had wired controllers that used a numeric keypad and a dial to control the player. It was very, very basic and had a wood panelling effect on the body. The games I used to play on it were Lock N' Chase which was a basically a Pacman clone but with the innovation of being able to build walls within the maze, allowing you to 'lock' the ghosts in. Pretty fun actually. Also a soccer game which consisted of matchstick figures running around and the graphics were so basic, the ball was square.
