Ultima Online could support millions of connected players over a peer-to-peer network? Allowing any player full access to adapt the world and create any content, of any genre, style or experience. All set across an infinite sized world?

I think it's a bit of an offense to pair DreamWorld to Ultima and the legacy of people like Raph Koster, Starr Long et al. That game had a wealth of gameplay loops, progression, deep economy, and interesting world.

DreamWorld has no design, it's just all things. A plate full of every food you like does not make a good meal.
