Less "unnecessary" online games. To give you one tame example: Age of Empires 2 released in 1999 and is fully playable offline either as a single or multiplayer game via LAN. It has received two re-releases as AoE 2 HD edition and AoE 2 Definitive Edition. The Definitive Edition does not work offline for multiplayer games anymore. It is still the same game with updated graphics and engine but it is still just Age of Empires 2.

In order to play an actuall "Local Area Network" game, you first need to connect to the online Xbox Service. Only then will "Multiplayer" be available as an option and only then you can actually select "Local Area Network" as the "server region" for the match.

All for an updated re-release of a game from 1999.

I was at the AoE 2 DE launch LAN event at a Microsoft Store with big YouTubers and everything. They could not play LAN because right at launch, the online servers crashed due to the load. No one played a multiplayer game at this LAN...
