Having coded for both the C64 and the Amiga, I agree completely. The Sprite hardware in the two is very different.

AFAIK Rygar uses 32 pixel wide Sprites instead. Still an AGA only feature, but not 64 pixels ;)

I guess the issue is mostly one of speed. Virtua Racing (& fighter) both ran at high frame rates, most of complex the Amiga 3D games don't come close to that.

AFAIK the chip SEGA used is some sort of RISC monster. In a previous thread on Virtua Fighter for the 68030 it turned out that this chip is probably faster than a 68030@50MHz.

IIRC, some non-AGA games that did have AGA versions (such as Civilization) also ran a lot better on the A1200. In part because of speed, in part because of extra memory.
