Those are just there to give other buildings the bonuses they need.I hate the fact that two of the set pieces don't have connection bonuses or productions
What chapter are you in?I WAS excited about a new set, then saw the size and what it did.... not so much now
In chapter 15 the set gives me goods equal to 9x9h runs.
As a 2x9h player this means the set is worth as much as 4 level 31 buildings so I will save 100 squares of factories and another 120 squares of pop.
I managed to get 2 sets on Beta which fit in 72 squares with a value of around 500 squares.
That's 17 expansions which don't count against me in the spire tournament.
