Caution, if you're thinking that your server choice will have no effect on the PvE aspect of the game, you might be in for an unpleasant surprise: It looks like the promised "guesting" feature that allows you to join your friends' worlds and explore the PvE aspect of the game together won't be implemented upon launch.
This was posted in guildwars2.com's news section yesterday:
Guildwars2.com said:In time, we’ll also introduce free “guesting,” which will allow players to visit other worlds as guests as long as they have friends on those worlds. This feature will be free, but guest players will not be able to enter World vs. World, and the Power of the Mists bonuses from their home world will continue to apply to their characters.
So if you're looking to play Guild Wars 2 with your friends on day one, make sure you all pick the same world for your characters. While there have been hints that world transfers will be free for a limited amount of time, a clear official statement on this matter is still pending.
