Since we are on the topic of reworking weird / useless mechanics in the game, I think the japanese consulate, more to the point, the japanese isolation,needs to be reworked a tiny bit,there are some techs which are essentially useless, some are a tiny little bit too good, and some are just outright weird.
- Clan offerings: instead of making castles spawn a useless samurai after 45 seconds, replace it with spawning tokugaua instead from the consulate, not castles lol (move the tech to age 4 and remove the card from deck). He can be respawned at the consulate. Increase cost to 700 export.
- Bushido principles: Now also changes japanese consulate unit costs from export to part export (50%) part food/gold (50%). Daymios train units a 10% slower. Cost increased to 500 export.
And now the elephant in the room: Meiji Restoration
Instead of advancing wonderless to age 5 and being at a huge disadvantage because of that, allow it to improve the bonuses of existing wonders by a specific percentage:
Shrine wonder: supports 10 more population and boosts shrines by an additional 5%
Statue wonder: reduce cooldown of informants by 50%
Shogunate wonder: 10% faster training time for units
Golden Pavilion: 5% more to each bonus
Torii gates: 10% more XP bonus.
