eye of the north question

I was wondering if I buy eye of the north will have acces to the other previous games like nightfall or factions.

No

Eye of the North is an expansion to the other games and cannot be used alone. It has no character creation.

You need to purchase at least one of the complete games, Guild Wars, GW: Factions, GW: Nightfall, to play the game.

EotN is an expansion
Factions, Nightfall and Profecies are stand alone campaigns. U need one of these for eotn, but you dont need more then 1.

If you have 1 of the 3 campaigns, then u can access Eotn. Like if u got eotn and nightfall, you can only go to nightfall and eotn and not proph and factions.
