I'm going to buy Esprit and have a couple questions... Do you get the full 2 CDs worth of content with the download version? As much as I'd like the printed manual, I don't want to wait for shipment. Are there any reasons why I should get the boxed version that I don't know about? Does the voucher have to be used up in one order, or can a leftover balance be carried over for later purchases? I want to make sure I understand about the ecosystems. This works in Esprit, right? I understand there is the expander pack Ecosystems. I also see in the demo there are certain materials that are ecosystem, whereas the others are solid growth. Do you have to own the expander to make use of these? Or does the expander pack just allow you to make changes and make ecosystems out of your own stuff? What exactly are the differences with ecosystem and solid growth? I'll appreciate anything else you want to inform or warn me of me of. Thanks.
