This is why I've been mostly playing without resources in my games, the components are too powerful early on then useless later in the game and the buildings aren't really worth it from what I've seen of them and I plan on modding in some building that will overlap with some of them.  

To balance them throughout the span of the game they need to be upgradable.  Also they are using up a resource, why do they need to be so damned expensive?  That is your trade off, you are expending a resource, you will not get that resource back, the building cost should be, probably a bit more expensive than buildings of the same tier but not enormously so as they are now.  I'll leave it to the devs to decide if the upgrades will require additional resources or not.

I agree the first buildings were fairly overpowered but the nerf bat hit them hard now they are barely worth it before the resource cost

The anti matter plant and that were over nerfed.  Will be adjusting prior to release.

I think all buildings that give big adjacency bonuses but do not receive them need to be looked at. Most of them are very weak. Their outgoing bonuses encourage you to place them in a central location, but when you do, you miss out on a lot of incoming bonuses which makes them much weaker than they appear at first.

I took the challenge and I realized that I was wrong. The uses for the refinery are very corner case, so much that I will echo the building is underpowered.

Why is the pleasurepark useful? Approval is really easy to get. 2-3 techs for the starbase upgrade and you are in at 100% until mid/lategame... then just trade for the approval resource. Problem solved.

Refinery is kind of useful on occasion, antimatter plant (while nerfed badly) is great for boosting Hyperions... Particularily since you can still build multiple antimatter plants

Thulium is borderline worthless. 

The Pleasure park give RAW gross income and quite a boost and is available very early in the game... it is a pretty usable improvement on wealth planets or planets that alternate between industry and wealth which is quite common in my empire.

The pleasure park is basically a casino. It doesn't give approval on its own, but it gives +6 raw income, which is really good, and +3 approval adjacency, which is VERY good, but it doesn't give income adjacency, making it balanced. I don't even care if it giving income and not approval is a bug, it should stay.

I argue that the durantium refinery should be buffed to +3 instead of +1. Pleasure park is fine. Thulium archive and Antimatter plant are useless, especially considering how rare antimatter is.
