Is it possible to play Age of Empires II HD on an intranet? Is there a way I can specify the host ip? My version is the Steam one. Let me know if further details are needed. Thanks.
If you begin a multiplayer game where all the players are on the same network, AoE2 will automatically run it as a LAN game.
However, Age of Empires HD multiplayer requires a Steam connection to run. If your network has no outside connection or you are trying to avoid a firewall on a public network, you won't be able to create the game.
This also means you can't share copies of AoE. You still need one account per player.
