Camelot Unchained features three distinct realms (Arthurians, Tuatha Dé Danann and Vikings) as the protagonists in a bold new vision. If you've seen our teaser/trailer, you know this is not a rehash of Dark Age of Camelot or any other game. The piercing of the Veil and the events that have flowed from it have changed the world in very unexpected, dramatic and quite magical ways.

No cross-realm chat in CU. I've seen the logs of what players so to each other, I can just imagine what they would say to the other side. No thanks.

All I can say is that no RvR-based MMORPG will ever have an equal population on each server unless the developer applied strict limitations on the game like "No new TDDs right now sorry!" and we are not going to do that. We will do what we can to ensure that all the realms are as balanced (population wise) as possible but at the end of the day, it is up to the players to self-select. We will "encourage" people to play the less popular realms and we will certainly put the design effort into making sure that the smaller realms get plenty of design love to figure out why they are less popular. We will also do things such as real-time bonuses to the under-populated realms to make them more attractive to play but like I said, it's up to the players.

I’ll start by addressing the issue of realm pride as that is the first choice that players will make during CU’s character creation process. There are truly no “good guys” or “bad guys” in CU, at least in the traditional sense, as each realm’s actions are motivated by their instincts for self-preservation and survival.

The Tuatha De Danann are simply trying to restore balance to the world and to begin to prepare for another apocalypse; the Vikings are looking for new lands to settle on and rebuild, and the Arthurians are looking to unite the world under Arthur’s banner and civilize and tame a hostile world.
