Is my google-fu weak or is the Starter Edition technically the demo? And am I not able to play it without a guest pass? I can see that it will be available after 30 days from release as a demo so I'd have to wait until then?
(I'm not asking for a guest pass, I think people who have bought it and will get a late delivery deserve it first.)
Yes the starter edition is just a demo (same content as beta) and right now requires a guest pass.
From what I remember WoW was the same, but after a while blizzard just let everyone have access to a trial account. If you want to try it in the first 30 days it may not be too hard to get a guest pass. They are rare right now (i still need one), but once more peoples CE arrive over the coming days, more will be available.
