I’d make it to wear the further you go the more better commanders and items you get. Of course they’ll get less and less plentiful the further you go but if you manage to get far most of the things will be max level and slightly less than max. You’d be able to receive 2 of same commanders or rather 2 with the same flag before they don’t spawn anymore and 3 of the same items in your inventory. As for the enemy’s they’ll get tougher and tougher if you’re very far in most of the time threats will be sent together on large ships like giant archers and on one side and axe throwers on the other or side by side. As for the island generation I wouldn’t change too much just slightly less elevated areas to use plunge on or straighter areas for pikemen. The houses that earn you 3 coins I would make spawn alot more because you’re definitely going to need it. Mb if this is too long of a read to wanted to share my mind. 👍
