Pretending we are alone in the cosmos is a dangerous thing... there are hidden civilisations of Atari Jaguar coders, Acorn and Atari groups, C=64 web servers etc.
Other interesting cults would be those programming Amiga emulators for Sony PSP, Dreamcast and GameCube!
I consider myself lucky I had a ZX Spectrum 128k +2 as well as a Sega Master System. The quantity of games and their variety was probably a key to me seeking out more from a home machine.
I spent as much time meddling with Workbench as I did playing Sonic!
