I suppose at some point this will cease to be news, but the franchises that made LAN gaming great continue to turn their back on it, providing a long slow obituary for the service. Command & Conquer is the latest.
Command & Conquer 4 will not only require a constant online connection, it'll end support for LAN as well as dedicated servers, an Electronic Arts designer tells Destructoid. The reason is because the game's global player progression system will all live remotely on an EA server. While it allows players to log in to their account from any machine, it's incompatible with dedicated server support.
EA promises, however, that it's overhauled the game's networking to deliver a more stable experience, with quicker entry into games.
