How do planet adjacency effects work?
I've just started a new game, and am exploring the various options. I've run into the planetary details screen. Each tile can support one building, and one population. Thing is, I noticed these little + arrows next to some buildings, and hovering over them gives me adjacency bonuses.
What causes this? Is it specific buildings that improve the spaces around them? Is there a list of adjacency combos?
Best Answer
According to this dev article,
Buildings can also be constructed in tiles, and they often have adjacency bonuses for the resource they are producing. Therefore it will be advantageous to construct your power plants in proximity to each other, to achieve optimal efficiency.
so the adjacency bonus should come from buildings that produce the same resource in an adjacent tile.

Answer 2
Its because that tile (the tile that is providing the adjacency bonus) is where you first sent down your calony ship to colonize the planet, or in this case as it is your capital planet it is actually the planetary administration, or capital of the planet. The capital of the planet is what provides the adjacency bonus. Hope this helps!
