I must say that I think with Aeternity we are going to have a stew of various elements that when fully cooked, will result in one of the best games ever.
Mechanics wise, it will blow anything else out of the water. I've always felt that the game systems should enhance realism and depth to the game, and automated combat systems do not do that.
In terms of the environment, I suspect some of the best role-players you will find will flock here.
