I needed plans for a generic embassy in Manhattan (okay, Doctor Doom's Latverian embassy). I wanted the grounds (with perimeter walls, guard towers, a secure, gated entrance, and helipad). And I wanted a second story, with a third story round tower and a bedroom for a prisoner.
I typed that all in and seconds later, I got exactly what I wanted— plus walkways around the grounds, a loading area, secret escape route, laboratory, guards barracks, reception room, throne room, "Latverian cultural gallery"— absolutely perfect for a gaming layout, and none of which I had explicitly asked for. Color me impressed. (Duck.ai).
The first time around it also gave me a full color layout (suitable for a board game), in gloomy, Dr. Doom-like colors with furnishings and moody bits of whatnot suitable for the theme. Too detailed for what I wanted, but nevertheless, impressive.
