I guess the same can be said for Atari ST. Not as advanced as an Amiga, but you could do some clever tricks (and later models DID have a blitter, I only found that out much later. Again, not as good as the Amiga one, but nevertheless, better than nothing). There just weren't that many great games and demos that showcased them. In retrospect, I think some Atari ST demos may actually be even more impressive than Amiga demos.
I have to agree. Some of the Atari stuff is just mind-boggling, especially considering the limitations. I've had many very interesting chats with Wiztom of Aggression (he's a game developer at Housemarque btw) about Atari and how the custom HW differ from Amiga.
