FF6 is my fave of the Final Fantasy's. Old school graphics, but best gameplay of the bunch, in my opinion.

A co-worker of mine is liking Final Fantasy 11 (online). I stay away from MMORPGs ever since getting majorly burned on Star Wars Galaxies, though.

If you're into more traditional RPGs, Neverwinter Nights is pretty cool. I believe it has 2 expansions out now.

I'm a big fan of Morrowind, too. Highly recomendable.
