Halo 3: ODST, The Counduit or Killzone 2?

[Xponent]

Although I hope The Conduit will be as good as some have built it up to be, without having played any of these games, I think that Halo 3: ODST is the obvious pick here, based on the quality and reputation of its developer.

Having said that, I'm not a huge fan of modern FPS's anyway.
