I don't know tbh what you don't understand about using the other landmasses for historic rp and for imaginary trade. That's the purpose, they'd not just be decor (and for real now, my English isn't THAT bad, that this wouldn't have been understandable up until now).
On the other hand I of course don't understand either.
What I don't understand I made clear in my previous post:
1) Why are you against the idea in general? (Because obviously you dislike the idea whether the new lands would have a purpose or not)
2) Why do you seem to be the only person that I met in TSP up until now, that doesn't think that there are at least undefined other continents on the TSP planet?
