Did you try Shessar's workaround above?

It shouldn't default to that folder, but every now and then something happens which causes the save dialog to open in that folder. This is a problem you can encounter in most windows programs, because you really want to let the dialog remember where the users where saving the files instead of forcing them to a specific directory each time, and this remembering is taken care of by the underlying Windows system, not the program itself.

The important thing in any program is to save your work where you want it, not where the program defaults to, as having control over your own data files makes it much easier to both find them outside the program and handling things like backups.

It actually used to be a bit more difference, because DD3 was the product that contained the specialized dungeon tools for making things like rooms and connecting corridors and such, so without DD3 you wouldn't have these specialized tools.

However, as of the latest CC3+ version, these dungeon tools are installed in all CC3+ installation, so that isn't a concern any more.

So, the big difference comes down to two things:

• Amount of artwork: The dedicated products (DD3, SS2, SS4) do contain more artwork in a given style than the various dungeon issues in the annuals, which are a bit more light-weight.
• The style: Down to what visual style you prefer.

With the exception of Symbol Set 1 & 2, you'll find the entire list in the Tools menu -> Add Ons

Only way to check SS1 and 2 is to go into the new map wizard, and under overland and dungeon respectively, see if you have templates for these.

Bundle is a very nice deal even if you own CC3+ itself, but need some add-ons. Each of the three main add-ons in there (Dungeon Designer, City Designer, Perspectives) normally cost more by themselves than you can get the entire bundle for. And the bundle also contains much more.
