One thing I loved about EQ was that, at least in certain places like Kithicor forest, the behavior and presence of certain mobs and NPCs was different at night - different usually being much more dangerous. That really made the game immersive and more fun for me.
It looks like Pantheon will have some of that; e.g., some NPCs go into their homes and shops at night. I hope there is more to it, and expect that there will be.
This kind of attention to detail in an indie game is part of what makes this game special.
