By the way, I have a copy of Left 4 Dead for the 360. I am committed to not playing this game until I can play it in co-op mode with people I know.
This requires people I know to own the game (and have a Live Gold account). If you've scored a copy, drop me a line (and your Gamertag, if I don't already have it) so we can hook up for some zombie-surviving fun.
EDIT: I'm posting this on my blog, so obviously I'm favouring a fairly generous definition of "people I know". If you're reading this and you're not obviously an incarcerated criminal you should probably take it to include you.
