With my history with MMOs, it should come as no surprise that the PvP in ESO would get the most scrutiny from me. DAoC continues to be my favorite MMO of all time and even in my time in WoW I spent a lot of time PvP’ing. PvP will make or break a MMO for me. If your MMO doesn’t do PvP well or doesn’t do it at all, I am much less likely to spend a significant amount of time there.
It is strange that Elder Scrolls Online focuses so much on PvP. They basically took a single-player, quest driven RPG and made it into a MMO that focuses strongly on PvP throughout. This seems like a very strange decision and one that takes a certain amount of courage. I am not sure how many Elder Scroll fans would classify PvP as one of the things they were looking for if they designed an Elder Scrolls MMO.
That being said, if it is well done, it will succeed. There is a large contingent of PvP players in MMOs and they will support a well made game. Admittedly, there are few truly well made PvP MMOs out there. Guild Wars 2 tried mightily with their WvW PvP but I believe they missed the mark with a few poor decisions and an engine that was simply incapable of keeping up with the large amounts of players displayed on the screen at any given time.
