I've been at the Age of Empires 2 Definitive Edition release event in Berlin. It was held at a Microsoft store with German YouTubers. Head of European Marketing for Xbox was there as well.

They couldn't play a multiplayer game because right at release, the servers were overloaded and the new version did not have a LAN mode at launch.

The whole purpose of the event was to have a kind of LAN / multiplayer gaming with the community and stream it.
