I just went and checked Japan's First Look vid around the point where
they present the Meiji Restoration bonus. As an example, they build the Holy Site district (immediately, probably for the sake of showing of the stats), and point to different locations for where it can be built. Normally, the Holy Site gets the following adjacency bonuses:
Minor bonus from adjacent districts and forests (
+0.5 each)
Standard bonus from adjacent mountains (
+1 each)
Major bonus from adjacent natural wonders (
+2 each)
I'm assuming the city center is counting as a district, because it added up to the district adjacency bonus.
When choosing where to build the Holy Site, the first spot had forests and a mountain - the forests said "+1 for
every two adjacent forests." This could mean that the coding doesn't register a 0.5 yield, but instead leaves a "null" value from the adjacent forest (and normally districts) until the amount of adjacent forests reaches an even value (2 giving +1, 4 giving +2, 6 giving +3, etc.), which if Meiji Restoration really doesn't add an
additional +1 from adjacent districts but instead only buffs it up to +1 and leaves it at that, it could make things difficult to fix via tricking the coding.
Anywho, back to the topic - the presenter continues to move over a tile with a forest, the city center, and the theatre square, and it only shows "+2 from adjacent districts." Later, they move to a tile with 3 mountains, the city center, the theatre square, and another district (encampment?) and gave +3 for the districts.
According to the UA, and I quote from the current pre-release build: "Meiji Restoration - All districts receive and
additional standard adjacency bonus for being adjacent to another district." This means Japan is supposed to get the +1 yield of a standard adjacency bonus
in addition to the +0.5 yield of a minor adjacency bonus. The minor adjacency bonus, however, is calculated as +1 for every
two districts, so that needs to be taken into account. The final bonus, then, should be calculated as follows: +1 per each individual district, along with a +1 for every two adjacent districts.
Put more simply, you
should be getting these bonuses:
+1 for one adjacent district
+3 for two adjacent districts
+4 for three adjacent districts
+6 for four adjacent districts
+7 for five adjacent districts
+9 for six adjacent districts
This is a pretty big deal - you could potentially get insane boosts to your districts, potentially within reaching the medieval era! I understand that this might have deserved a nerf, but that's beside the point.
So what
is the point, hm? The point is that
the unique ability gives the wrong stats. It specifically says that you are supposed to get the standard adjacency bonus (+1 for every 1 adjacent)
in addition to the minor adjacency bonus (+1 for every 2 adjacent). However, the video clearly shows the districts giving +0.5 for every district, or +1 for every two districts - a
minor bonus, not the
standard bonus, as stated in the build. The video itself is much less explicit, stating vague "bonuses" without going into detail.
However, since the pre-release build is meant to reflect the final product, that means that
Japan is supposed to get an additional standard bonus, and not a
minor bonus. I haven't seen any pre-release streams of Japan and the only Japan pre-release vids I can find is the one by Solar Gamer, and so far he hasn't built any districts adjacent to at least two others, so I can't tell if the additional standard bonus is implemented yet, but in any case,
it is supposed to be there.
Edit: I'm gonna go and make a post in /r/civ about this issue. Whether or not it's a bug, or if calling the bonus standard instead of adjacent was a mistake on Firaxis's part, I'm not sure - but considering that some Firaxis employees are occasionally active on there, the issue might get their attention, and be addressed.
Seriously, I'd be shocked if it was intended to stack. It would mean possible +9 from rainforest for Brazil, and +9 for districts for Japan. And Japan could build dozen district next to each other easily, so it would be an insane bonus. My money is on simple +1 bonus.
