First fangame i played was the original Sonic Robo Blast back in '01. Made a couple of pointless Kilk and Play games then started using Games Factory after playing one of the early Time Attacked demos.
Think I took part in 3 or 4 SAGEs, probably won't enter again, lets just say my creations don't quite live up to modern expectations
EDIT: FFFFF- Thirdscape! Thanks for mentioning that Andrew. I've always thought that the story would fit well into the modern 3D Sonic era, least a damn sight more than S2K6...
