@JoelOak It's a very, very tough threshold. My last game I got 14 points. Sometimes those buildings just don't have enough synergy and the churn just isn't there in solo play.
Doesn't take long for coins to start looking like they come from antiquity, what with all the wear on them.
1944 nickel on the left, 1986 on the right. Notice the features rubbed off Monticello.
Enjoying solo Sanctum. Easy mode seems very easy, but it's helped me learn the game as I completely bungled my first play in almost every possible rules error way.
This time I played right and I felt like such a badass as I crushed every demon under my archer boots!
