Age of Empires III: Definitive Edition uses server-based online multiplayer with cross-network play, so players on the Steam version and the Microsoft Store (Game Pass) version share the same universal lobby and can play together. You sign in with an Xbox / Microsoft account for the online profile. Because there is no console version, crossplay here means Steam and the Microsoft Store, not PC-to-console.
You can play solo and offline against the AI in skirmish and the historical campaigns — no connection or other players required. The cross-network multiplayer is a separate online layer.

Up to eight players in an online match, in competitive or team/co-op setups against other players or the AI.
