Already a bit annoyed that Blizzard have decided to scrap LAN and dedicated server support for Starcraft II? Angry at Infinity Ward for not including it in Call of Duty: Modern Warfare 2? A big Command & Conquer fan? Then I think you better sit down now.
Because, surprise, Command & Conquer 4: Tiberian Twilight won't support LAN or dedicated servers either! Lead Designer Sam Bass told Destructoid that it's all because of the global player progression system, which you might or might not care about. You will be able to access everything you've unlocked from the central server, wherever you are. Good thing you have to stay connected at all times while playing, then!
