Playing "Diablo - Lord of Terror" campaign for Neverwinter Nights.

With PRC (a zillion extra classes and stuff) - and I'm having a ball with my Fighter/Tempest/Weapon Master.

It's - by far - the best player-made mod that I've tried for NWN. A very faithful version of Diablo with a ton of optional sidequests.

I'm constantly surprised by the excellent balance and the attention to details.

It's easily 30-40 hours of Diablo goodness with the best character development system out there.
