I was looking at getting Radlands this morning too. It has been on my list for a year or so and keeps coming up as having something special. I really like the Radlands theme also (possible 2000ad inspired).

I've played Architects of the West Kingdom one time also and liked it a lot.

I've never heard of Yamataï either, which is surprising because we love Kanagawa and have played it many times. It looks equally elegant and calming.

Thanks for these recommendations :^)
