Nope, so far there is only one server. Since this game is free, im guessing that people dont try to play as often as they can to get their money's worth out of it, becuase they dont have to.
Plus as someone else stated, this being a Demo version of what the game will be, not as many people are interested. Two years ago, I was looking for a good MMORPG to play for free. This site came up and I wasnt interested. But now Ive come back, and Im hooked. It just may take a while before more players join in on the fun.
And also, if you think about it, wouldnt more players on at once slow up the sytem altogether? I know Im sounding greedy, but until more servers are put up, I think its fine the way it is.
