I don't spend enough time here
20th February 2007
My friend who has installed Winter Assault and all of the patches up to 1.51 can even find the same chat rooms as I can. I have Dark Crusade installed and also have all the patches. At one time he could find a chat room called Segmentum Solar which I haven't found yet. Then he restarted the game and found Cadian Gate which I were in and he connected to a game I'd made but I was using Winter Assault. Now when I choose Dark Crusade he can still choose the Cadian Gate chat room but he can't find my game.

DC and WA obviously have chat rooms calls Cadian Gate, but all the games in the WA chat room are for people using WA, if your using DC you can't play a game with someone using DC, the same way someone using Soulstorm couldn't play online with someone playing Original Dawn of War.
you will only be able to play together if you both are playing the same version of the game.

Just as absent said. While the names of the lobbies are the same, they are not the same in themselves. It would be kinda weird when you actually think about it.
