The earliest games I remember playing were on the Commodore Vic-20, they were text-based or 'write your own'. I never really used consoles probably due to the time experienced 'programming' on the Vic-20.
After the Vic-20, I was given a C-64 then Amiga by my parents, and this was when I really got into sim racing for the first time. The first major simulation being Geoff Crammond's F1GP, and eventually this led me to move through most simulations, and end up working for simulation developers myself.

Apart from racing simulations, space games like Elite, Wing Commander and the X series from Egosoft have been a solid focus. I use them to 'escape' from work.
