While they are not going to be the same type of Mmorpg in every aspect, they could both be out around the same time ( same year) and will share a lot in common and going by TESO screes and KOA screen they will look similar and they both have singleplayer openworld sandbox-ish counterparts compare that are them selves very similar.
The main things i can see right off that sets the 2 apart is that TESO will focus heavily on pvp while Project Copernicus looks to focus more on pve, and also Project Copernicus will use the same real-time action based combat system that the singleplayer game features where as TESO has opted for Hotbar based action combat rather than the real-time action combat of the single player TES games.
Point of the thread, who else here things we could see a showdown between these 2 new Mmorpg's in 2013 and what might the outcome of that be ?
