Gamerscore Wall

I have hit a wall in gamerscore and its really annoying me. I see people getting 1k's all over the place. And every game I seem to be getting I can't even pass 200 in the thing.. Like Afro Samurai, Civilization Revo... and so on. But I need some motivation to start getting my completions up because its pissing me off. Hopefully GSL will help.
