LF something with a big/active community.

Hi all,

I was just looking for an MMO with a large and/or active community. I'm really big into the community aspect of games, like guilds and the sort. I' not looking for any particular type of game, but I'd prefer no MOBAs and that it be F2P. I recently tried Aion, and while I did enjoy it, it didn't draw me in. Also tried Tera, but there was never anybody in my level zones. So, yeah. I'm just looking for a game with a good community. I don't really care if it's PVE or PVP focused.

Thanks.

EDIT: I'd also like to add that sys reqs aren't a problem.
