My first experience working in a creative industry was working for Wide games in Brighton on two projects between 2000-2002. Prisoner of War and Pilot Down.
I was also very active within the modding community for Unreal Tournament, designing and making levels.
These days I mostly tinker with unity, creating strange and experimental games for my own amusement.
Here are a couple of videos of people playing those first games:

Pilot Down
