Anyway, I thought I read you could now delete zero point games from your gamertag. Am I imagining that? If not, how do I go about doing it?[/QUOTE]
I'm going to answer my own question.
Hit the guide button, go left and click 'Achievements.' Any game that shows 0 gamerscore, including original Xbox games, will pop up an extra option to delete with 'X' at the bottom of the screen.
