no
Beat the game.
Follow the main storyline
you dont
yes
It depends which Halo and which Fable. If you mean Halo 1 vs. Fable 1, then I'd say Fable, because Halo 1 doesn't have multiplayer on the Xbox. But, if you mean Halo 3 vs. Fable 2, then I personally like Halo 3 better. Halo 3, even after you beat the campaign, the game has longevity because there is multiplayer, whereas once you beat the Fable campaign, you're bored with it.
In necropolis, beat Artix v.s the undead
You can't. He Ran away.
you can only get rid of a quest if you beat the game sorry =(

no you can find them through out the game before completing it
