I heartily recommend Dark Age of Camelot (DAOC). I have NWN and much prefer DAOC. I haven't played Morrowind so I can't speak to it. DAOC is of the online variety so constantly get to interact with other live folks, although given the right character choices you do not have to group with others to succeed.
It's extremely addictive, so much so that it measures each character's play time in 24 hour days.
