Returning player needs advice.

Let me start by saying I had a 360, sold it for a PS3, then sold the PS3 two days ago and picked up the 360 again.  I actually got $400 trade for the 20 gig PS3, so it paid for my premium system.  I know that is all stupid so please keep those comments to a minimum. :)

What I need help with is online game communities.  I have GeOW, COD 3, and Lost Planet.  I was thinking of buying Chrome Hounds or Battlefield again, but I wanted to know if there is still alot of players of these games.

Oh, and what about RS Vegas?  Is that a pretty active community?

Is the community playing RS vegas pretty good?  I mean I played a little GeOW last night and find it alot like the Halo 2 community.  By that I mean a bunch of younger kids swearing alot.  I thought the games I played last night were fun, but a more mature group of players is always welcome.
