Like everybody says, it is much more interesting to have a variation of topics to talk about. I find that General Chat in particular shows everyone's views and personalities- adds some human into the blocks of text! I've met some great people on these forums who i've goten to know first through the GC forum and later on MSN- its builds friendships.

Also, if you've been on the forums for at least a few months, you will notice that nearly every single thread about Final Fantasy (if not all of them) is repeated again and again. I don't know how many times i've seen "hoos ur favrit carikter", so to be honest, the variety here is what keeps people on the boards.
