@billymagnum: Composition and proofreading aren't comparable. Writing and composition in music are often done by separate people on many occasions. Hans Zimmer collaborates with many music creators for his compositions for example. Not composing the music doesnt necessarily mean he didn't have the talent and inspiration involved in writing much of it, although if he was listed as the composer then clearly there's still fakery involved. The story doesn't make clear whether he was involved or whether he did none of the work.
Like what was said above, the rule is designed to prevent a player from "camping" in front of the opposing teams goal, away from the game. Since the rule only applies when the pass is being made it allows for "through-balls" which allow someone to run past the defence as a pass is being made for him to run onto. A player only only counts as offside if they are considered to be involved in the play, which invites a grey area but doesn't slow the game with excessive calls by the ref.
To be clear, did he write the music but use the composer to ensure it came together properly or did he do literally nothing? There's a big difference between the two; if its the former then I would cut him some slack. I pity him either way.
I can't rember where but I'm pretty sure a MS guy hinted that we shouldn't expect for there to necessarily be more Halo anniversary games just because there was a first one. The way he described it was that Halo 1 Anniversary was also special because of the launch of the Xbox brand.
