Perhaps I misunderstand what you are saying here, but none of this, aside from the the shape of Dwilight is "designed"
Well, yeah. That's why I noted I was talking specifically about map design.
Not sure what the misunderstanding was about.
Merging the continents is the only method of increasing opportunity.
I'm not a fan of that idea.
Apart from Anaris already mentioned, different continents currently have different rules (SMA, 1 turn/day) which I'd loathe to see abolished.
Do you mean some kind of symmetrical war island, designed for X number of predefined teams? Kind of like the war island we have now, but more than 3 realms?
Not at all. I'm only talking about eliminating obvious flaws like the aforementioned Riombara peninsula or Dwilight's unfortunate shape.
I do have plans to improve island geography; however, I don't think people would be very happy in general if I just swooped in and completely rewrote their islands, any more than they were about the Ice Age.
I think there will be a big difference here: everyone will be on the same page, so players would not feel being unfairly screwed.
