The only thing that makes sense to me, is if ED is creating a fully fledged terrain editor software that is easy to use. The Nevada map is only the first test subject required for disclosing what is needed of such software, being developed in parallell. When Nevada comes, the editor will be released to the public as well, and will enable any serious group to develop any theatre they wish, fast, with focus on content and not technicalities, either paid or for free.
