Ooh sorry for taking this thread so far off-topic, but to others thinking of trying it, amazon.co.uk seems to have massively cut the prices - I think I can get all 4 (i.e. including Eye of the North) for £22, buying them each separately.
Given how far off GW2 seems to be, and how bored I am with wow . . . think I may have to buy my second ever game
Edit: am assuming windows vista edition is fine for me playing on windows 7? They're so cheap I'm kinda looking for the catch But the wiki seems to think it's fine.
