What buildings did you miss out on and really want?

Cool Brown House
Super Collider & black hole
Mayan calendar & god


Started to play too late to get them, and, unlike the Halloween items etc. (that came back for donuts, when the first time they were free), haven't been available again.....hopefully we'll get a chance to buy them sometime.

Would be glad to pay fresh doughnuts for them...... :D
