Which game has had the best post-launch support?

What game do you think has had the best post-launch support out of any 360 game? I think it's either Halo 3 for its multiple map packs and constant Match-Making updates, or Gears of War 2 for its multiple map packs and all of the updates it has had since launch to make it a better game.

Halo for map packs,updates,ODST multiplayer disc,Bungie.net,avatar clothing and accessories,themes,gamer pics and Waypoint,just off the top of my head.

Halo 3 seems to have the best support.

Halo 3, TF2, nhl series is the best post launch of all sports games though.

Halo 3 without a doubt.

Halo 3 has some really great support. Halo 2 did also, as Map Packs were still being released up to the release of Halo 3.

Bethesda has been really good with DLC for Oblivion and Fallout 3. But yeah Halo 3 too.
