I had a few problems when i first got the system and i thought my Xbox had a problem. So i started to worry. Then i contacted the folks at Microsoft and talked to them about the problem and they figured out that it was the game. So i took the game back to the nearest Best Buy and they exchanged the game with no problems and when i got home i popped in the new Call of Duty 2 and it played with no problems. So im thinking that with those earlier glitches that were reported werent from the sytems but from the game itself. My Xbox 360 works great i give this new system 10/10
