I was a member of WROCC for a while after discovering RISC OS is still barely alive as a platform. The scene itself is rubbish though, overpriced and underspec machines needed to run the latest version of the OS (sound familiar?!), not many resources for the older stuff online.
I never really regarded the platform as a gaming one, I only ever played a demo of Lemmings 2! Although it did inspire me to get the full Amiga version!
