Witness the Japanese co-prosperity sphere globe. You've seen tall games, but this is super tall.
- 7048 development across 48 stated provinces.
- The highest developed province is 171, the lowest developed stated province is 141.
- 81 tributaries dutifully providing me with an extra 490 mana per year.
- Nearly every nation in the world paying tribute to our greatness. No disloyal subjects.
- 4.3k income. 1m army force limit, 2227 naval force limit. Dominating world trade from Japan with nearly 2000 lightships.
- Producing insane amounts of goods to the effect that only 1 dyes province produces over half of the world's supply at 34.96 goods produced.
- It's currently 1707 - if I continued to 1823 I'd estimate an additional 5280 development for a total of 12,328 development across 48 stated provinces.
The conventional strategy for playing tall by stacking development cost modifiers can make development cheaper than this, but only for a limited amount. Using holy orders across 13 states and 48 provinces resulted in 17.7 mana per development, regardless of terrain or existing development.
Check out that city sprawl! If only two of my provinces were independent, they would make #3 great power, lol.
Could have made everyone a tributary, but it got to a point of playing cat and mouse by losing tributaries whom are allied to the nation you attack. Also nations max out giving 12 mana/month and some of these are way over the threshold, so ideally they would be broken up a bit, but it would be very annoying (due to previous reason and them eating each other back up) and possibly inefficient due to costs of releasing.
Two perfectly balanced cultures is the trick. The highest dev province that isn't mine is Constantinople at 55, which appears as a dull orange in the development map mode, washed out by Japan's glorious green.
With only a single province of dyes - which has 34.96 goods produced - I produce over half of the world's dye.
I have a couple of provinces scattered around the world used for making tributaries (border connections), but many aren't centers of trade as I hadn't originally intended on keeping them. Yet with 1887 lightships, I dominated global trade from my island. Nippon itself has double the value of the next highest node (English Channel) and funnily enough, 449/542 of the trade value in Nippon is produced locally.
