I did a search and didn't see that anyone else had mentioned this soooo....

Yep. It's a remake of U6 with multiplayer. Free as well. You'll find me as Gwynydd if my attention span holds up.

Me and my brother are both playing this.  Surprisingly fun if you were into old-school Ultima years ago.

EDIT:  Yeah, I played this all bloody night.  It's exactly what it purports to be:  Ultima 6, down to the last detail, with multiple people running around.  It's even simpler and uglier than UO, but there are no elves!
