Age of Empires fans have been waiting for an announcement by Microsoft for quite some time now. Originally, there was meant to be an announcement at the Inside Xbox livestream, but that announcement was pulled and postponed to what now seems to be E3 2019. To tie fans over and build that hype up a little bit, Microsoft has decided to announce that the Age of Empires II: Definitive Edition and the Age of Empires III: Definitive Edition will be coming to Steam when they launch.
According to the blog post on the Age of Empires website, players will be able to "enjoy these games no matter where you play", and that "by releasing Age of Empires I, II, and III: Definitive Editions to Steam, we are letting you, our fans, decide where you want to play, explore, and create new experiences with our games." The blog post finishes up by saying that more information will soon be released on the Steam cross-play support, most likely at the E3 2019 keynote on Sunday, June 9.
