On the surface, this appears to be a great buy-you can download a sample, which is excellent.
They promise high production values-they're not bad.
They promise flexiblity (quote):
"All models include Blank Floor Plans of EVERY floor, so you have the option of creating your own perfect floor plans to match your own games/scenarios."
What they do not mention is that the pdf is locked, so if you had hoped to copy & adjust those blank floor plans, or use the floor plans in a virtual tabletop, you're out of luck.
If they had bothered to add that simple fact (locked pdf) on the prodict listing it would be no problem, but all you get is a 'zip file' listing.
Good thing I only bought one set to check the hype.
