I'll probably do what I did with the other Halo games get the single player achievements and forget the multiplayer ones, Im not paying for gold just so i can get a higher gamer score
People do that? I mean, they ONLY play the single player of Halo? I mean, the single player campaigns are usually pretty well-done in a Halo game, but...I don't know, I've just never seen them as the reason people play a Halo game.
I'll get multiplayer achievements but only when there's things like free gold weekends or when I feel like getting a month of gold, I game online on my PS3.
