Going off topic I know (because we were talking case designs) but speaking of the ST/STE lines, wouldn't the better solution for Atari after launching a weaker machine [compared to the Amiga 1000] have been to simply bolt on a 16mhz 68000 instead of forcing recoding of all games to get any improvements with an inferior 2 channel 8bit DAC and their less sophisticated blitter setup?
I say this because if the PC (spit!!) market has taught us anything, consumers like having their favourite software run miraculously faster when they eventually 'upgrade' their computer with a newer one. Had Atari done this then ALL games would instantly have improved with a 16mhz 68000 not just polygon games. The most the code would need is a little tweak for the main game engine loop timing or nothing at all. Running Gauntlet 1 on a 16mhz ST gives a very satisfying arcade conversion which is light years ahead of either Garrison or Gauntlet 2 on Amiga. Lotus II also runs almost as smooth as the Amiga version with a 16mhz 68000....sound is another issue on Lotus
Luckily Gauntlet 1 is 100% software sample playback on the ST though so in that case still worked a treat.
(Gauntlet 2 was probably some of the worst coding ever on the Amiga and even inferior on the ST to its predecessor)
