Mimo: You do realize you are acting as the poster child for why game publishers are uncomfortable with DRM free games, don't you?
You do realize that you're acting like the poster child for the brainwashed for why companies get away with everything because of lack of critical thinking?
Yes, of course, because I'm sure everyone's looking forward to the future when there's absolutely no non-hotseat multiplayer available for the game at all because the authentication servers are down. Nevermind that these are my own computers all on one IP in my own home. My friends were quite interested in the game, until they saw the hassle and decided they'd rather play a board game. So potentially excited new players, who may have gotten their own copies after a kick-ass LAN session, instead turned into "meh"s. That's exactly what restrictions do.
*sigh* It used to be that the multiplayer component was the freer part! Spawn copies, demos that did multiplayer...
They have (they claim, anyway) working LAN code in there... once you jump through all the ridiculous hoops of have an account/bind account/log in/authenticate/lobby-on-the-servers. Just enable without the lobby restrictions it so it can actually be played as a LAN game.
