[R&F] The best adjacency Civs

[Sostratus]

Australia/Netherlands probably get the better immediate bonuses,

A nice feature about the netherlands is that river tiles don't actually take up space and leave you with a lot of options. Just putting a campus and theater square on a river and next to each and one other district (CH? city center?) is already locking in +3 for both. Japan has the greatest potential, but, you have no flexibility: you have to surround it with districts. This leaves fewer spaces for wonders, improvements, etc. For example, you may have to break a farm triangle or rip out a bonus resource. The other nice perk is that a river doesn't sacrifice any hill tiles, so and IZ can still get the full benefit of the +prod improvements around it. Also, who hasn't gotten a natural dutch +8 IZ and just felt efficient?

Not disputing japan's crown in this- hail to the shogun, baby!

Yep. Especially if you're treating it as "who can get the quickest +3 for the era score bonus/policy card bonus", then the Dutch have a big edge there. You just need one mountain to get a +3 campus spot, or, alternately, they're one of the rare civs that can get a +3 campus in the middle of a flatland just by having it in a triangle. Of course there's the flaw that sometimes you get the annoying case of the river not running through the mountain, and now you have to figure out which spot to use up.
Of course, they also only get that bonus for 1/2 the districts overall. Japan has the edge in that their bonus is for all districts - one of Japan's largest unappreciated bonuses is making super-harbors. It was more valuable before they added the +2 for being next to a city, but Japan is one of the easiest civs to get a big harbor bonus, which converts to a production bonus when shipyards come online. Thinking about it, they can run a pretty damn sweet commerce hub/harbour/xxx triangle, and can afford to have that away from the city-centre if they don't need that.
