Agricultural and residential decorations

[Aeralis]

I'm fairly certain these don't actually do anything? Residential are definitely just for decoration, but agricultural confuses me. The greenhouse is the only agricultural building that gets efficiency boosts from decorations, and it even has a wide effect radius, but it doesn't actually produce anything so efficiency seems to be useless for it. And farms only get boosts from the farmland path tiles.

Just want to make sure there's not some aspect of the efficiency system I'm missing.

Higher efficiency should give discounts on research items, it does for the other research buildings so presumably the Greenhouse should get the same benefit.

It's not really worth building a bunch of decorations to get the research discounts, though. The discounts aren't much, and the decorations are very expensive, especially when you place multiples of them. Doesn't balance out at all, you'll end up spending way more materials on the decorations than you will just paying full price for all research items.

I'm not sure about the residential decorations, though. I have a bunch around my houses but I don't think they do anything.

Having said that, I am weirdly enjoying the "grind" required to keep putting down these decorations, though. Like a single tree costs me a few thousand materials at this point... lol, I am a sucker for this game. Currently putting trees around my entire farm field and it's becoming a real end-game project, haha

Ah, I didn't realize efficiency reduced research costs, so that explains that. But yeah, it seems super not worth investing in. Decorations are so expensive to unlock, especially the agricultural ones, it seems like it would be a net loss.

Decorations have an escalating cost, but only for that specific decoration. You can always put down a ton of decorations and then delete them afterward, which is perfect for any that reduce the cost of unlocks. Especially because you can easily pick up and move them around if you just want to swap around different buildings to unlock stuff easier. I think there are 4 different ones that benefit from Commercial? It just makes everything so much easier.
