That's exactly where I'd like to go, creating an entire fantasy world from the ground up just by pushing a few buttons, then combine it with Sigurd's find of that awesome German terrain renderer, then get something like the Sims to populate the place and I could have my own world/ant farm and with some powerful 3d apps I could walk among the people. Might need to get some of Pixar's computers or ILM's for that tho
