You (as a member of the USA) were once part of england, france, spain, and the netherlands. Would it be fair then to lump you into those civs? No, because the US is very culturally distinct, as is Norway with Denmark. The polynesians shared a very similar culture and language throughout, and while at first I did oppose them, I have grown to love and accept the side. The celts on the other hand shared little with each other and are a very ill defined area, with much debate as to who is celt and who is an offspring, sister clan, influenced neighbor, unrelated, etc. where as what we call Polynesia is usually an agreed upon set of islands
You shouldn't assume what my answer would be, and you also missed one of my requirements "wouldn't be in otherwise". The US is always in these games and probably rightfully deserves its place. It would be hard to argue that BOTH Norway and Denmark would deserve a spot so I have no problem with them being put in together, since historically they were together at one time.
If the USA was culturally insignificant enough to not be considered into the game, than absolutely, I would be OK with them being grouped with one of those countries. The problem is that they are a distinct entity that would be in the game, so it makes no sense to do so.
I would always prefer the individual civs to be in the game as opposed to grouped. However, if they are not going to BOTH be in the game and they were historically together or historically similar enough, I have no issue with them being together.
I hope that clears up what I mean.
