The game automatically saves to the and the cloud.

You do not need to finish your multiplayer game in one sitting.

Though Anno 1800 does not feature a "Legacy LAN" button in the traditional sense, players can achieve the same effect:

One player acts as the host and creates a new game session.

Yes, , though it functions primarily through the Ubisoft Connect infrastructure . While there isn't a "legacy" offline-only LAN button, you can achieve a local network experience by connecting your PCs to the same router.

Nota: in alcune versioni la schermata può mostrare solo partite internet; in quel caso creare una “stanza privata” e invitare tramite Ubisoft Connect è il workaround migliore per sessioni locali.

Allows players to purchase critical items and seeds without fighting over trader inventory.

Even for LAN, Anno 1800 requires an active Ubisoft Connect login. The game "heartbeats" to Ubisoft servers, so an internet connection is usually required to start the session, even if the data stays local.

In older strategy titles like Anno 1404 , players could connect computers directly via an Ethernet switch and play without an internet connection. In Anno 1800 , the multiplayer infrastructure is completely central-server oriented.
