This.
The only pieces that would fit into my city build would be the arch and the normal wall. But with the lack of proper windows, doors and roofpieces its pretty much useless. I won´t spend 10 bucks for 2 pieces that would have use to me.
And to be serious. With the tos in your neck you are not even allowed to build a wall around your base on official otherwise people will report you for landclaiming.
