Do more people play Halo 3 or Halo 3 ODST on X-Box Live?

B.Q. If you can, can you please explain to me how I can find a ranked CTF match?

Hey i love halo3 and odst. You cant really play halo odst xbox live. You can invite people to campain and stuff but halo 3 is the major xbox live source. Oh and you cant find ctf games you can go to squad battle (6vs6) ranked the types of games are assult, CTF, and Slayer
