I just saw some how to play videos hitting my Youtube feed. While I concede the point that it is different than the base game of Sagrada I don't feel as though it brings enough to the table to warrant buying it. I really enjoy Sagrada, but I'll be passing this one up for sure. Maybe if it hits a deep discount I'd give it a try.
I've been curious myself and I'll accept this as the answer. Ty for finally solving this for me.
