I actually didn't do anything to fix it, it popped up naturally. I believe it just popped up as soon as I bought the Passing DLC and loaded the game. It was a pleasant surprise to say the least.
The real question is why you feel you shouldn't take it as advice but as an attack. It may be an opinion but the average player doesn't do what you do and it isn't a smart decision. You should never bring yourself to play terrible games like Darkest of Days, Fairytale Fights, or Wallace & Grommit because there will be persons who will be impressed by a gamerscore that's higher than their own for the most of a minute or two; it just doesn't make sense and it can't prove anything positive.
The Last Remnant aside you play a ton of bad games. You should sit and think for a second how pointless it is leveling your gamerscore to the point you play terrible games/play for no reason but earning points.
