This is why I stuck to modeling ships, bases, etc.. I never had much fun with anything organic, or land based.. though I've done a few things with slight moving parts.. Guns, rotating sections for Gravity, etc..
Also I've obsessive complusive, so everything I do has to be very mathmatical, and organics is the opposit of that, as are terrains..
I vote chrome.. Looks nicer if done right, but it always a pain
