Is it according to your play style that you fill out at the beginning of the game?
Personally, I like low populated area's, for example; At the beginning of World of Warcraft i chose the least populated server (7 years ago) and with the implementation of cross-realms, I quit. I couldn't get to a realm where there weren't 100 people outside of Stormwind, or even random mobs of people, where i used to chill alone, if not see maybe a few others around.
Yes, I know this is an MMO, and I love seeing people in cities and area's that are naturally dense, but when I want to quest or go to an area, I'd much rather not have the same density of people there. Another example of this; In World of Warcraft, Goldshire, Crossroads, Darkshire, and a few other places on low populated servers weren't very dense, which is a positive (In my opinion).
I've come to the conclusion that questing, and adventuring alone best suits my playstyle, and I have no problem coming into contact with someone else in the world, but to an extent.
Does anyone else have this concern? Or knowledge as to how its going to work?
