To be honest im looking forward to play Mythos way more than Hellgate, i mean hellgate could have been nice but that concept died along the way, Mythos was developed to test gameplay stuff from Hellgate and it turned out to be way more fun than the actual game. The Mythos CB barely had like 2 zones you could go but you could appreciate the gameplay quality, besides Mythos actually had a "real" diablo feel to it. Originally, it only had the Diablo II camera type but in the menu it had a "enable third person view" button that didnt work in cb, but seems they already implemented that.

So in short i think you got totally "Flagshipped"
