I say the same thing here about the petition that I've said everywhere else you've spammed this around the forums:

I wonder if you 'petitioners' for a mulitplayer campaign have actually really thought about how it would work? 'Cos TW campaigns can last quite a long time, even taking a single turn for a single player can go upwards of an hour when his empire gets large. So, given that players aren't going to be online playing for several weeks continuously you're going to have to compromise on something. If you want to keep the camp map and not too bothered about the battles then we have a pretty servicable RTW multiplayer campaign mod already. If you want to keep the battles and are prepared to accept a more stylised campaign map then the Lordz are testing an online multiplayer campaign run through a website.
