Guild wars nightfall, factions, or eye of the north?

i have guild wars prophecies and im gonna buy one of the above games i just cant decide because i dont know much about them. what is the land like (I dont like playing in dark environments, im not scared i just dont think its cool) and do you have to have nightfall or factions to have eye of the north?Guild wars nightfall, factions, or eye of the north?
I'd recommend buying either the Trilogy pack or Factions Platinum edition. You get more than one game for your money and it's the best deal. If you really enjoy GW then you'll want all 4 games eventually so that your characters will have access to all the skills.



About the darkness thing.....what do you mean when you say you don't like dark environments? You dislike the dimness because it's hard to see your surroundings or you don't like evil demon infested storylines?



If it's just dimness issues then you can fix that. Go into the prefences menu (F11) and adjust the gamma slider bar on the graphics tab. I turn up my gamma all the time when I'm in the forest. Urgoz Warren and Blacktide Den are especially hard to see and the gamma will solve that.Guild wars nightfall, factions, or eye of the north?
nightfall is relatively dark so i'd stay away from that, factions ends up being somewhat dark and so does eye of the north



from a pvp perspective you'd be best off getting all three, but if you only want one for both pve and pvp content by far my favorite is eye of the north then, nice and snowy and a bit different from prophecies/nightfall/factions in terms of how they handled the story and the quests, very cool.
