So my friend told me about a glitch/trick? on how to get rid of any game along with its gamerscore.

You have the game you want to delete in your console, you boot it up so its the last game on your played game list, then you eject it and put in one for which you have 0 gamerscore, boot it up so that game is the last on your games played list and eject the disk. then you go to your gamerscore, and you can press x over the 0 achievement game and it will ask "are you sure you want to delete?" you press A but then you quickly press down X up X after you press A and the same message will come up again, you press a and voila both are gone!

Falout 3 is nowhere to be seen on his profile and his total gamerscore has gone down, so I tried this with Oblivion, its not in my achievements list on my xbox but its still showing up on Xbox.com and my last played games. Not sure whats going on there.

EDIT > Maybe M$ are on the case, there is no sign of oblivion on my account but my gamerscore has not lowered and its still visable on xbox.com! I really hope they don't patch this, I don't want to have to play through oblivion for hours to get all the achievements

The real question that remains here is, why would anyone want to do this?

For those that like to complete the achievements on each game its nice to be able to delete games you don't like/don't have anymore.

They still need to find out a way to get rid of trial arcade games from your games list.
Even though I played a trial and deleted it,
it still shows when I compare games with someone.
All I see are my achievements that I earned, and after that, a huge list of 0's.

Is there a trick to actually increase the gamerscore? Now that would be useful.
