Duranthium for this ship, Elerium for that ship, Thulium for the other one. And the really powerful ship needs Antimatter and administrators.
I feel like I have to devote all my new Citizens to Admin training so that I can keep building constructors for mining starbases.
It's still early so I'll give it a fair chance, and I really LOVE not having to create constructors for starbase upgrades. But in the effort to simplify one aspect to gameplay, it has become exhausting and it feels like we may have introduced an imbalance by bureacratizing another aspect.
