I stopped caring after Reach, that bloody achievement where you have to leap off a cliff and knife an elite was bugged for me but I spent forever just leaping off that freaking rock to bounce on the ground. Then to add insult to injury that freaking achievement that ended in 3 gamerscore sets my teeth on edge. It forever ruined the nice 0 or 5 with 3 or an 8 ;_; I loved Reach but it put me off gamerscore forever. Now I play games for fun instead of completionism, and I actually enjoy it a lot more :D
