Trying to understand.
So, a Player, aka someone who spent money to play, would essentially be paying to be a stagecoach driver. And the people inside could then in theory go do dishes whilst someone who is paying player drives them around the continent.
My question would be thus. Why would anyone pay $25 minimum to drive a stage coach?
Now, NPC driven coaches that would deliver people to player cities via a loading screen similar to harbors, or driving them to harbors would be doable and very beneficial. There's would need to be a building added to the city planning so that the city would be registered to the line, perhaps even locked behind research. I would be all for legit, era-appropriate fast travel. We have horses, we have wagons. Not a big leap to passenger wagons. Being able to go from Broken Hills to FFA in a moment would be awesome. Except we have harbors for that.
There's some problems with this however. First of all the D-Squad aka the griefers and gankers are already screaming bloody murder because good and neutral don't drop any gear. Which is how it should be. Now we take away their ability to spawn camp harbors and low level areas.
