Speculation regarding custom titles has been confirmed!
As suspected, the new GuildLeader can give out custom titles AND ships, so it looks as if the monarch abilities of the original game have come across largely intact. The ultrabot, Aristotle Landry, has apparently not chosen to use those abilities yet. Will he, now that he has competition? Time will tell!
(p.s. and congratulations to The Reverend Doctor Buckaroo Mu!)
