I can't help with the latter; I'm taken (sorry reproductively-healthy people)!
So I didn't get a PS4 because I'm broke, and I didn't buy Battlefield 4 because it is broken. I'm hoping there are some people in that same boat but still want to play Battlefield 3 on PlayStation 3. I fell of the wagon a long time ago but I'm trying to get back into it. If anyone wants to start a casual clan or simply play a few rounds every now and then, let me know.
That game is surprisingly active but I find myself playing Operation Metro with maximum tickets because people seem to cooperate in those games. I would love to see the rest of the game modes again.
Fair warning: I don't have all of the DLC (only Back to Karkand).
