Short Answer. Wait until the Marketplace is ready and see if it offers content you would like to use, then buy the subscription. You can all the features of RW and save a lot of time.
Long answer:
Yes, it is a lot of work...now. But this is one reason why you may want to consider a subscription. Once the marketplace is live, you will be able to buy adventures that other people put the work into, with all the cool features of RW. Exmortis's reply reads a bit harsh to me. I think there are some people like myself and, from his response it seems Exmortis, who use RW to build and manage campaigns and enjoy the process even though it *is* a *lot* of work. But there are many others who would rather buy a module, but have all the features of RW to enhance that content.
