It's good to grapple with ease-of-use. We're talking about a Mac product here, and mac users won't up up with crappy interfaces.
But let's not lose track of the realism which is the selling point of GA. So that realism will be enhanced by:
- allowing more fish in the tank
- allowing fish to cast blobby shadows on the gravel
- adding bump maps so we can see the scales on these fish
I know, I know, this has been addressed before
