Microsoft is running a survey about the Xbox Live service-- what you like, what you don't like, what you play, etc etc. Technically it's attached to a 2-month free trial offer, but I'm sure they won't mind hearing from you if you're a subscriber already.There are plenty of places to fill in "other" under reasons why you're going to subscribe, or have already. Feel free to put in "Halo 2" someplace.
