Age of Empires: Definitive Edition will pioneer one of the previously unseen arts - it will feature cross-play between PC and PC. Microsoft are touting it as crossplay between Windows Store and Steam but the feature is still mind-boggling.
Epic Games are basically giving Microsoft free marketing these days and the latest instance of this is the supposed crossplay for Age of Empires: Definitive Edition.
One curious fan asked Microsoft on the game's official Twitter account whether they would need to purchase the game on Steam once again if they already did so on Windows Store.
Naturally, the answer was yes, they would have to purchase the game again in order to acquire the license for both stores but Microsoft didn't let an opportunity to advertise generous "features" in the reply.
The answer kicked off by claiming that Age of Empires: Definitive Edition will support "crossplay" between Steam and Microsoft Store. There is nothing crossplay-like in the whole affair here since both storefronts are on PC and the game itself is not available on any other gaming platform.
Technically, Microsoft could justify leaving their player base unable to have multiplayer games with Steam users because they host their own servers and Valve allow developers to utilise Steam's API to implement multiplayer features, essentially making it two player bases for the same game.
Call of Duty: Infinite Warfare had a similar problem where those who purchased the game from Microsoft couldn't play with those bought the game on Steam. Then again, barely anyone remembers this due to Infinite Warfare being such a smash hit that only Anthem or Fallout 76 could make it look good.
PC players playing with other fans of the same game regardless of which store they bought it on has always been a thing and Microsoft touting this as a noteworthy feature is quite absurd.
The only reason it really popped up is Epic Games' recently-acquired infamy following the string of exclusivity deals that built timed walled off gardens. This allowed Microsoft to advertise themselves at every corner by selling their products on stores other than the Windows one.
