Yeah, while it's fun to scroll around and see what stories people are trying to tell through this medium, it'd be really cool to have some actors moving around in the world. Riders on the roller coasters (which seem to be among the most fun things to build in any building game; even when the tools don't make it easy to do so), people roaming around exploring (and occasionsally being chopped up by the chainsaw guy or eaten by the scary smoke monster thing, or turned into a newt when walking over a black magic altar, etc.) would make this absolutely magical to just watch and play with. Not to say it's not cool today, as it is, just that if the dinosaurs roared and flung cars, it'd be a mild form of ecstasy.
