Heck YES! I am that lazy! Self proclaimed world's laziest DM and proud of it.
A question that really has to be asked is: Why am I buying a product only to have to do umpteen hours of work adapting it on my own? That's fine for those who enjoy reinventing the wheel with every product they buy, but, for me, I want to buy a product and with the minimum amount of effort possible, plunk it down into play. It bugs me to no end to buy a product and then have to completely rework it in order to use it. If including a couple of pages of information as to how this can be slotted into this or that campaign, then it's all good. I wish more publishers would do this. Include ideas for how to fit this into a low magic (Eberron), mid magic (Greyhawk) or high magic (FR) campaign.
Isn't the point of buying stuff to make my life as a DM easier? Why should buying a new book mean MORE work for me? If I'm willing to shell out the thirty bucks or so for the book, then, hey, I want to save thirty dollars (or MORE!) worth of work.
