In terms of enthusiasm, sure, but the majority of folks who bought the game played through the single player stuff and then shelved it... just like any other non-mmo game.
I agree with this. It seems like a pretty odd decision. If you are going to create an easy to use toolset, why wouldn't you have a small team make a campaign with it? Bioware seemed to make a very basic campaign with NWN, it was surpassed in quality by the fan community fairly quickly, but at least it came with something to play out of the box.
It's pretty early in the development though, so I guess time will tell.
