Amazingly the Xbox support can't help. Fancy that.
My Xbox 360 will only play one game, Rainbow 6 Vegas 2, although I think it is one of the best games ever I would like to play some others. Don't reply with rubbish about intialisation, clearing the cache or maybe the other games are not compatible. I have tried all the support remedies with no success. I originally played all of them but now only Rainbow is recognised.
I am begining to believe the Xbox has in built failures to force customers to upgrades. I know this is possible and it is also possible to have the require upgrade programmed into a server. Why, because I am a programmer. If I can do it so can Microsoft.
