I'm no expert in binary, but, if what you're saying is true Teh Smithers, his sig. is supposed to be how it is and if one does understand binary than they would've noticed the error (like you did).
As for the original post, I don't have 1,000/1,000 in Halo 3 and doubt I will get it because I hate Lone Wolves games and, even if I were to play Lone Wolves, I doubt I would be able to get them because a few of them seem too hard. Only way I can see myself getting them is if I were to boost for them.
