1) It does not matter if there is a game that makes more money than a game you like.
2) It's pretty ironic that this Halo game has quite a few Call of Duty additions...(kill cam, custom loadouts, sprinting, rewards for doing well...you get the picture)
If you really felt the need to hate CoD, you'd hate this game too and stick to H3 or Reach or something.
3) Seriously it really doesn't matter what happens with CoD if you're a Halo fan. I don't know why you think it does.
I really don't. If you hadn't read, which I take you hadn't, i only made this post to reassure someone that sales were still good even though that person got apprehensive from seeing few people on Halo.
