Guild Wars 2

So, I pre-ordered the game back while it was in beta. And I’ve been playing it on and off, but I recently saw the digital deluxe now has new items. Am I eligible for them? Or am I out of luck, because I bought it over a year ago?

Well as with any product that goes on sale or gets updated.
Unless it’s a matter of hours, no. It’s a tactic to get new players.

You don’t get money back if your tv suddenly goes on sale 5 months after you bought it and the same goes here.

You can however buy the extra’s in game.
