Keep it as generic as possible. Of the suggestions, I think the castle and the pirate ship would do best. The house must by definition be of a specific fashion and period, thereby limiting the size of your market (think how different a television, or a hi-fi is now, compared to even 15 years ago) The aircraft; similar. How many people will want a Cessna? The castle and the tall ship on the other hand could be fudged to work in several centuries, plus fantasy. Cost is a big problem. How about selling them in modules? Say $40.00 for the basic, then $25.00 for each of the add-on bits. Agree, a low rez taster might help. I think it's the kind of thing you do because you love it, not because you want to make money. But you've been there before Anthony, right?
