In the MMORPG area there is today Darkfall which is kind of a spiritual successor to UO in many regards (full loot, anyone can kill you outside cities and so on) but in first and third person 3D. The original game had its issues though and is closed down since mid November because of the release of the now much hyped sequel Darkfall: Unholy Wars (a.k.a Darkfall 2.0), coincidentally coming out on Wednesday next week. It was also greentlit on steam in record time (like within 24h) so there's definitely craving for games like this out there.
