Well i beg to differ, on any game forum (its true that most ppl dont post if it works fine), but not one post to say that it works by anyone, well it does work, but if u consider the client machine lagging on everything for up to 30 seconds a great multiplayer experience then i suppose it works great!
I am rather amazed that not one person has came onto the forums and told ppl how cool it is multiplayer, probably because noone has actually had a cool experience with the game multiplayer.
I think it was a developer that posted there was a synch problem, that is why the internet option was dropped, but clearly the problem still exists in LAN gameplay.
It appears to me, that the multiplayer option was totally rushed and was never working properly, but they still went ahead and released it, now that is not neccesarily a bad policy, if a patch to fix the problems is expected shortly after release, but no fix looks like its going to make appearance, partly becuase of the possible add-on.
If thats so, then that draws me to the conclusion that they do not intend to fix the current game at all (multiplayer wise), therefore the main selling point of this game (being multiplayer) is fubar for me.
NOTE: Nothing wrong with my config either, the multiplayer system simply fails to work within any reasonable capacity.
