The people that post on here are a fairly small portion of the members. Notice on patch days that a ton of people are on the forums. True, this place hasn't been too active lately, but neither has WoW really. I kinda wish more people would get into swtor. Its a really cool game, just doesn't seem to attract the same size crowd as WoW.
I'm thinking that maybe there are a finite number of MMO players.. Each time a new game comes out, it drafts players from the other games. If that continues, then then there won't be enough players on each game for anyone to enjoy any of them.
