I bought Halo 2 from a car boot sale at the weekend for £6 but it wont play in my 360... tried it in a normal xbox too and it doesnt work - so obviously its a crap disc! I found halo 2 on newsgroups so downloaded and it works fine. Not really bothered about playing it online... wanted it more for local multiplayer with my mates! My question is... can I apply the update that xbox live wants to do? and also can I play on live on the 360??? or shall I decline the update and stay offline?
