Guild Wars Trilogy question

[Pattyo121]

I already own prophecies and factions. I want to buy nightfall. If I buy the Guild Wars trilogy am i able to add nightfall to my existing account and just keep the other 2 games? What I mean is does the guild wars trilogy only belong to 1 account or are you able to add separate games to different accounts?

The trilogy is just one key with access to all 3 campaigns, you should just buy Nightfall alone and add that to your account.

Darn. I was hoping it would go on the daily sale and be cheaper than nightfall by itself.

Yes, I own prophecies but not through Steam. Been hoping Nightfall or Factions would go on sale soon for around $10 so I could buy it then be able to log into Prophecies too on Steam.
