I recently was locked out of several games and Netflix because they wanted additional email addresses on my Xbox live account - I already had the primary and a back up - now they have 2 back ups! And this wasn't to play games over the WAN - this was to play games locally while logged in as my XBox Live user!
I had to deal with this last night so I could play a lego game locally with my son. I've never been particularly happy about having to have a live subscription for streaming video services and this was even more annoying. As it stands now I've just about had it with consoles.
