Age of Empires 4 is the second largest Xbox Game Studios title on Steam by number of players, surpassed only by Halo: The Master Chief Collection.
Age of Empires 4 was the protagonist of a very successful launch on Steam: the strategy produced by Microsoft was the second most-played title by Xbox Game Studios, peaking at 69,366 concurrent users.
Remaining in the context of the Redmond house, only Halo: The Master Chief Collection (here the review) did better, with its 161,024 players, while the other Xbox exclusives all score lower numbers.
An excellent and deserved result for Age of Empires 4: the review of the game confirms its great qualities and the many contents, starting with the four campaigns and the new maps.
