Well, it's no Ginkgopolis...
I scored 113 in a game with my wife.
I had a small set of land with a temple in the middle and had the sun revolving around them every 2 actions. Each time, I collected 4 VP (temple + 3 surrounding land) and then later 7 VP due to the City Hall.
Pretty much 1/2 of my points came from this.
I assume this is legit?
Correct. it is +3 per temple so if you had another Temple it would have added 6.
Our games we usually score around 120-140 usually winning score is round 130-140.
