Ok, I just had one of the most incredible experiences.
I ran the Epic Citadel map from the UDKGame, brought the console down and typed 'Fly'. I then proceeded to fly up to one of the towers and stuck my hand out as if to touch the stone wall as I flew by. It was an amazing and emotional experience. I can't believe how realistic it was! I really felt that I was there.
I'm sorry, but when they get the resolution sorted out, some people are never going to come back.
And I'll reiterate, the Unreal Engine is amazing in the Rift!!
Go immediately, put on a song you love, and fly around the Epic Citadel. Oh and make sure to touch the stone on the way by.
