When I view my profile on here, it says I haven’t played Halo 3 or the other Halo’s on my service record when I have. Just curious why it says that thanks.
If you have changed your gamertag at any point, your stats will still be linked to your old tag. If you still have access to play the old games, boot them up on your current gamer tag while connected to Xbox Live and play for a little while. Your stats should sync up shortly after that.
