How do you delete game history on games you've played on Xbox Live?

I was wondering if it is possible to delete your game history on games you play on your Xbox Live account, even the ones where you have gamer points. For an example, I have 75 gamer points on Spider man Web of Shadows but I want to delete its game history because I sold it. Is it possible? If so, how?|||Simple answer... No you can't once you have got gamerscore for a game you can't delete it. You can delete everything else about the game but it will always say that you have played that game befor.|||I don't believe it's possible to do it once you've gotten an achievement. I know you can do it if you haven't gotten an achievement, but once you have, I'm pretty sure it's stuck.|||http://goo.gl/AtG3c
