I'd almost say you should write it for a plain Amiga 500...
There's no money in a game designed for an A500 anymore.
Simply put, as much as you love you amiga, for christ sakes, UPGRADE!!! Sure there's not alot of support for amigas, but jeez, sell your old 1200 and invest in an A1 board. Motorola's 6X000 series is archaic by todays standards. Sure, you can use it, but do you people REALLY think a 68060 can handle running something like Unreal Tournament 2003 and that's a game I see Miggy Users whining for EVERYWHERE.
Also note that I said *I* wanted those specs. We don't even have an engine. For all I know, the game could run on an '040.
As for your comment about a Voodoo being old, blame Commodore and Amiga Inc for that one. You should be grateful that some engineers made a PCI bus that allowed your amiga to even use a, as you put it, 'a card (voodoo) that is way old compared to todays PC standards' in the first place. Correct me if I'm wrong, but the YOUNGEST amiga is a decade old, but you call a Gfx card, one that's only 4 or so years old and was the FIRST 2D/3D card in one chip, old.
We'll be getting new hardware once OS4 is out and believe me a Voodoo 3 is a powerhouse, compared to that crap Picasso IV or CV64 you may have. If you don't have the hardware to run the games, don't complain. While I like the HUNDREDS of old games I played on my A500, EVERY amiga user wants the eyecandy they see on PC boxes, including me.
I don't play alot of games anymore, 'cos they're all clones of something before, or they expect me to shell out 400$ for a Gfx card, just to play one game.. Amiga upgrades aren't more expensive that their PC counterparts, they just did it sooner. I'm not about to spend around $3000 bucks to build a machine that will play Doom 3. That's absurd...
If you had played Heroes before, you'd know that there's ALOT of graphic heavy moments in the game. If you can get a version of something similar to run on an A500, I'll buy you a cookie.
