I guess the problem is that for the 8-bit games there is a lot less required to master the computer, and also due to constraints the full game including graphics and audio can be done by one or two people in their spare time.
Pushing the Amiga and creating something worthwhile could take one or two people over a year (unless there is a site for Amiga code samples (hitting the hardware in assembler) that could speed up development) to get something done. Also the level of graphics the Amiga can achieve means that "programmer graphics" often won't be good enough!
I think Cammy has plans to get some games going, but it's probably early days. But yeah, it requires a few people dedicating some time to getting it done, and it helps if one or two are already experienced with the Amiga hardware.
