Fun is in the eye of the... tester? I don't mind broken/missing mechanics, placeholder systems and art. That's fine for me. I just like exploring systems, watching as things change, are added or done away with. It's a rare oportunity to watch as something is created.
Don't get me wrong, the vision of E:WoM in its final state is what drew me here, but to get in early, especially so very, very early, was going to be a special treat.
