Quick Question about Guild wars Trilogy

Okay, I'm thinking about buying the guild wars trilogy. I already have the prophecies campaign, and I heard that the guild wars trilogy package comes with only one code. If I input the guild wars trilogy serial into my account, will it work? I'm hoping that it will let me do it so I can receive factions and nightfall at the same time without having to buy them separately, since that is more expensive.

I'm pretty sure thats how it will work, and yes, you will only get 1 code.

The Trilogy includes the Game of the Year edition of Prophecies. What happens is it upgrades your Prophecies and adds Nightfall and Factions. It does not touch your characters or change anything you have accomplished.

like Darcy said, it doesn't change anything existing it adds whatever your missing whether it be a campaign or any upgrades like game of the year.

If you get the trilogy, you will have all the benefits listed in the wiki at:
