[quote name='radjago']You won't be able to go back and delete games from your history. After the update, it just won't show demos in your played games.
From the press release:
Xbox LIVE Arcade fans: we heard you. Trial games no longer show up on your profile. No more zero-gamerscore trial games on your played games list! (This applies to games loaded after the update; unfortunately, previously-played trial games will still be listed.)[/quote]
Excuse me, I have to go kick my TV in now.
[quote name='porieux']Hopefully you will be able to launch to old demos again in order to have them removed from your list, at least...[/quote]
God I hope your right.
