I found KotOR to be very well done and enjoyed it very much, but unfortuantely it has ZERO reply value. (the fact that it took me 4 days to complete the game means that it fell way short on the 'value' meter. Diablo 2 was a nice game, but you soon realized that the SP aspect of the game sucked. Finding sets and certain rare items was virtually impossible. In the end I lowered myself to using the D2++ mod almost exclusively. and that took much of the fun out of the game.
Many games that I bought in the past few years were very good, but fell short in the replay department. such titles as Far Cry, MoHAA, Deus Ex and KotOR were one shot pass through games. once completed, they left litle or no reason to replay.
Anyhow, that's my 2 cents.
Cheers!
