Both are 3rd party (overhead view ala Diablo II) solo characters and are quite good. Sacred is a HUGE game and requires an infinite amount of patience but it (and it's sequel Sacred Underworld) are well made, if not a bit impossible in some places.I have NOT played Sacred 2 or NWN 2 since, I believe, Sacred 2 has just been released and I just got a computer ca[able of playing NMN2.
Morrowind was OK, of not a bit big and very quest heavy. I did not play it's sequesl Oblivion for the reason given above for NMN2.
