I would prefer some good 2d games for 030, 040, 060... I think it's still possible to make "modern" 2d games on classics that don't look bad today. There are not so many 2d games that take advantage of accelerators and extra ram (Napalm requires accelerator but was quite slow on AGA... it looked as it was designed for chunky screens). Lo-Res high qualityplanar games would be perfectly possible.
I would love something like Diablo I on Amiga but I doubt AGA would be enough to move so many graphics on a 640x480 screen at 25fps. It would require quite a lot of optimizing or RTG directly.
If you like 3D racing there's already WipeOut2097. ;-)
