So, we've got a quarter-round floor with two fixed curved pillar walls and one freestanding one, with (a variety of?) 4x4 square floor insert(s). Looks good. And plenty of room for LED goodness for all of you light-fetishists out there!

Can't nest the 1/2 curve tower walls, so will have to improvise. Probably store them vertically like arches and fill in the space underneath with stacked floor pieces or something. Still won't be very efficient, but will have to deal with it.

Congratulations on a successful start to your venture!

Personally, I think it would make great sense to have the basic KS1 tiles available as an add-on, at a *slightly* reduced price. Those who want them right away can buy direct from store. Those who don't mind waiting until KS5 fulfills will wait a year, and DF knows exactly how many they need to manu...

If there were traps, I would buy them. I would switch them in and out during play.
If there were catacombs, I would likely get 1-2 sets, enough for one or two small rooms. I wouldn't be duplicating the Paris underground, after all.

I would have assumed it's on a boat.

Maybe you could turn this into a book? Or a series of them?

Chamber of Joy? (okay, okay, knock those smirks off your faces)

I have some clear Avery labels suitable for my colour laser printer. This just got me wondering how it would look on the dwarvenite sign....

Very nice!
