Got Halo Info?

[starcraft]

Hey guys,

 

Ive never been heavily into halo (dont even own the first one) but im finding it harder and harder to own a 360 and not be tempted to pick halo 3 up on day one.

 

Does anyone know info like how long the story mode is, what the frame rate is, and whether or not someone who likes shooters, but doesnt live for them, should buy this game?

thanks
