I like the fact that we have achievements/trophies and whatnot - it gives you added challenges other than just completing a game. But yes, the gamerscore thing is kind of pointless. They should do something else with achievements besides points though, Like maybe giving your little avatar thing a lancer when you complete gears 2 on insane or something. Maybe I'm talking out of my ass and going off topic here, but the main idea is: no, my gamerscore doesn't matter to me a bit (although I hate that it doesn't end with a five or zero...).
