Nobody likes Ludia

It's my favourite! Maybe I'll use it, someday

lol!
Anyway, I guess it can be more than one name ... In theory, each kingdom in the world might name it one way, according to its own culture

And, in time, a main name might appear.
Btw, the name it has, "Kingdom's Map", in Latin, would be
Tabula Regni. It could be thought to be a Tabula Regnorum (Kingdoms' Map). Also, Kingdom's Map suggests
Orbis Regni, or Regnorum.
