One concern is that the Tier 1 penalties sound hefty to me. I would be surprised if many of the buildings they unlock provide any benefit at all after that malus.
Just looked further and all the penalties seem too high.
I agree. The tier 1 penalties would stop players using them. -6% may be better.
Tier 2 - why do most have "+2:sick:, +2unhappy" ? Some are not as tasking as others.
Tier 3/4. Again %s need some reworking (some seem to severe).
