I honestly see no point in releasing it again. I have played the campaign so many times, same as any Halo fan. Casual players wont buy it again because they have finished, hardcore Halo players wont buy it again because they either have it or again have finished it a million times. All thats left in that game now is the Multiplayer. If thats on Live then I agree I wont be touching Halo 3 for a long time.
