So this is the way I basically look at it;
While slapping all the extra PCI bus things into an Amiga doesn't really make it more Amiga or less Amiga, the fact remains that there is quite a decent amount of software that will take advantage of RTG cards, workbench itself runs a heck of a lot faster than it does in AGA, looks a lot nicer as well.
So I have the best of both worlds in my system, 060 with RTG when I need/want it. Most everything plays extremely well in AGA (if they're 'native' games), and ports like the ones Novacoder have been doing work great either way. I'll be honest, for the most part, the RTG video modes have been used by me mostly to log onto aminet or wherever to download utilities. It's far easier and better to use Workbench at 1920x1080 with all the separate windows that it opens, than it is at 640x512, not to mention occasionally running into the fun times of running out of chip memory.
So while I'll readily play AGA/ECS/OCS games, I prefer the utilities to be in a bit higher resolution.
Granted I could have hunted for a Zorro based graphics card, but then are those any more 'Amiga'?
