Battleship or Borderstation, either. I say let the Kusari government decide and Igliss overrule. Is this asking for too much work? We're just trying to reach a compromise that might require mod work.
How do people feel about leaving the Honshu->Okinawa gate under the condition that when the Sigma-19 connection to Okinawa is competed (4.86 hopefully) it is realigned to Nagano? Then the gate in Okinawa could be removed, or moved to near Fujisawa and redirected to Nagano. (If it's necessary)
Here's an illustration of what I'm proposing for 4.86 in eastern Kusari and the Sigmas, where white lines would be gate jumps and blue jumpholes. I used the 4.85 map to get the geographical positions as accurate as possible.
Looking at it, all the angles make sense (though I think I put Sigma-19 in the wrong spot). The lane and gate in Honshu can be realigned to point towards Nagano.
Edit: I wrote the last sentence too fast, just fixed it.
