The Amiga scene is still popular, probably for the reason you said.

To be specific, the Amiga scene for a good while chased "coolness" with accelerated "monster"-Amigas.

But the focus shifted in recent years to treating "OCS" (ie "standard" Amiga500 with original chipset and 1mb,etc) more like a fixed platform like the C64 instead and imho has seen a bit of a revival since is mostly in the interesting part of pushing the OCS HW.
