The word "Networked" could mean either a LAN (Local Area Network) or an internet connection.

The word "networked" is instead used to distinguish from "non-networked" gaming, which involves playing on a single PC. This could be either a single-player game like the Starcraft campaign, a turn-based hotseat game like Civilization hotseat, or a simultaneous shared-keyboard game like Achtung, die Kurve!
