also since all 24 maps are coming on the second disc as well as forge, custome games, thearter all regular halo 3 multiplayer they might as well throw in the halo 3 campaign on the second disc also so we dont have to switch back and forth between 3 discs...halo 3 disc for halo 3 campaign...halo 3 odst disc 1 for campaign...halo 3 odst disc 2 for halo 3 multiplayer with new maps...they should just have disc 2 all halo 3 witch it campaign and all 24 maps.
