I left the official forums through word of mouth there about TWC. They didn't have things like mods available and, especially, at the time I was interested in modding RTW.
I think if we can get a couple of mods to take their home here and people who are active on their site, like me, could put in their sig that there is a paradox fansite with hosted mods and upload space for files people would start coming.
People do that often about sites for their own mod group.
It sholdn't be that hard as well being that the paradox forum is gradually gaining in activity as it is.
Paradox games are actually gaining popularity as well. They are getting more to the forefront with each title in sales as well as coverage on sites.
The thing is that most games where you have a highly active and popular following are not really that popular compared to any game. Even those flavor of the week shooters and RTS products. Also paradox games ARE popular enough to warrent a forum. There is a game series called Space Empires that is FAR less popular that has 3 highly active fansites that offer what we should offer for Paradox's products. So i'm sure a Paradox site should work.
Also having a paradox site doesn't exclude having a site for another game. I, for one, would like to see a Blizzard or a mmorpg fansite as well.
Also look at paradox's own forum:
http://forum.paradoxplaza.com/forum/
Its even more active than TWC. They have a similar type of user who posts there as well, we could leech so many great members to contribute to this site.
