I like the concept, almost like nation territories. Would blocks be able to be broken inside these claims? Can they be snake claims so that they can create a wall that blocks expansion from other nations, or do they have to be adjacent to other claims so that the expansion is more realistic. Can other nations "invade" these claims so that their expansion isn't blocked?

I like this suggestion too
It would.make it easier for nations to hold ports special places without the need of a town.
In my opinion I think they should have the same rules as normal claims and the same perms as normal claims

The idea is to claim territories without creating towns. A good thing to balance this may be that you need to create a sort of outpost or connect it to a unpeaceful town. The outpost would be an area, like a town homeblock, that is unpeaceful and can be conquered and occupied in a sort of minor sieges. For example, if nation A blocks nation B with this, Nation B may want to have those territories to expand, and after winning the battle can occupy it, and after a while it's theirs, nation's B claim.

The idea I had is to move conflicts from only being around unpeaceful towns to having battles even at 6000 blocks from the nearest town. For a more strategic gameplay, for certain spots control.

I may do some other posts to reach that goal. For example, there may be more areas that a nations may like to control for special benefits.

Main post would be cool for nation roads but I'd make them same price per chunk as towns. At this point, allow NPC's to make towns for roads which is basically the same
