Ogrork the Mighty said:Regardless of the legal issues, the Dragon compilation just didn't sell well. Period. So why you would bother potentially repeating that mistake is the real question that needs answering. If you can put forward an argument why large numbers of people will buy Dungeon when they wouldn't buy Dragon, then maybe it's a possibility at some point. But solving each and every legal issue is meaningless if the end product is just going to end up in the bargain bin...
I think what's likely to sell better is a huge hardcover collecting 75+ adventures and updating them to 3.5.
