Overall I enjoyed it, but i regret having finished the crisis quest. Feels like (over)paying for my granite pit. Sure the extra gems were nice, but to be honest I needed that granite harder than gems. Personally I find it a silly construction for a building, it holds 3K but only gives 1K. I misread/misunderstood the building's description and figured a heck I am trading in 3K for 3K. Well not. I will survive, but unhappily.
In short, the grand prize for ending all the quests, really does not feel like a prize, I think that is the main problem.
