Even if there was no games or anyother kind of software done using TV3D, just by trying it, you see what can be done with it (and it doesnt take 3 months of programming to figure out the power of TV).
As for the tools, I guess a map/world editor can easily be done, and it might suit your needs more than any already-made ones, anyway there's plenty of already made software to handle that, exporting files that TV can read.
my two cents....
