I only renewed mine for Games for Gold. It ran out end of December I think. I've not played Xbox Live since about October of last year when me and my friend finished off Borderlands 2 together. She's boxed her 360 away now.
I'm only keeping my 360 around for my exclusives and my large library of XBLA games. I've set my profile to private so no one can see what I'm doing. In fact I'm quite tempted to disconnect it from Live. I'm tired of seeing who's online wanking over CoD on a daily basis.
