I bought Halo3 September 25th.
October 14th playing Halo3 my 360 got the Dreaded Red Ring of Death.
About a month later I got my 360 back. It would not Play Halo3 but my other games worked fine.
Microsoft said it was the Halo3 Disc, I guess they have huge quality issues with Halo3 Discs.
The Replacement Disc did not work.
I called and they said it was probably still the disc.
My 3rd Disc Never Came.
Dec 26th I called for ANOTHER Disc.
It has still not come...............................
I paid $130 for the Legendary Edition of Halo3 and have not been able to play it for almost 4 months..... and Running.

Come on Microsoft get it together, Now!

I will continue to spread the word of my Dilemma anywhere and anyhow I can until I get my Halo3 Disc and the Thing actually works!
