I'm pretty sure the answer is "yes", but if I purchase Starcraft 2, and a friend or my roommate wants to play me using two of my computers both on the same LAN, do I need a second battle.net account and a second license? I ask because another of other RTS games can be played in LAN mode with only one copy, and that's often what I've done in the past.

    Certainly one of the most requested features is SC2 over LAN.

Starcraft 2 does not support LAN, so yes you'd need two licenses, but you'd be playing over Battle.net NOT lan.

    ...which also means that you need an internet connection! Commented Dec 20, 2010 at 14:27

    Didn't blizzard throw seven kinds of fit when they heard about the project and got it shut down? Commented Jul 20, 2012 at 5:18

You will need to be able to connect to Battle.net. You can give your friend a 14 day guest pass from your account. He should be able to play on that.


There is no LAN in SC2 (yet), only internet. Consider your LAN mates as arbitrary internet players. Each connects to Battle.Net, authenticates and plays connected to the internet.

So, yes, each one will need a separate Battle.Net account and a game license.


The main restriction: you need to login before start playing... Can you login from two different PCs simultaneously with the same login? I don't think so.
