Yeah Earth is still divided among nation states as it says that clearly in the Codex. However we don't know about some global government apart from the Systems Alliance. The only war that we know of is a Second American Civil War, which also comes out of the Codex. We don't know about Earth politics apart from what is listed in the Codex and the Earth pages.

As to what the game is, we can only speculate.
