I don't recall giving permission for my Gamertag to be used!
But it's okay. :3
On the topic of Gamerscore, this is mine;

, which I've gathered over 4 years, I think?
I've only got 1 100% completion, which is Lego Batman 2.
I'm aiming to complete Lego Marvel Superheroes too. Not got too far to go. Same is true for Lego Star Wars 3, and Lego Lord of the Rings.
I've got a single achievement to get for The Elder Scrolls IV: Oblivion, but I have to replay through the game to get it.
I'm sort of close for Skyrim (need to adopt child, 1k gold bounty in all holds, all daedric artefacts (waiting for Ebony Blade), All words of Soul Tear, buy and build all three houses (only 2 so far), tame and ride 5 dragons and defeat a legendary dragon).
I'm deffo downloading Dark Souls while it's on Games for Gold.
