Found something strange on my gamertag, ...

I went to look at my achievements when i was playing burnout paradise and found Half Life 2 from the Original Xbox at the top of my achievement list. I do have to game but havent played it on my 360, neither has anyone else in my family. Anybody any ideas how it got there? I thought at first that maybe someone had stolen my gamertag but i could still use it on xbox live and the email password that my GT is connected too hadn't changed, so i dunno what happened.Found something strange on my gamertag, ...
Strange. Are you using a gamertag from your original xbox? (Can you even do that?)Found something strange on my gamertag, ...

My guess is someone used your 360 without your consent. It`s the only answer that makes any sense, do you have brothers or sisters?
I know that some of the games I play also show up on the profile of my girlfriend, although she has never played them. This could obviously only happen to you if there were multiple accounts on your HDD which are being used. Since you said this is not the case, though, I can only agree with Almighty on the ghost hypothesis... :P
