I'm another that tried this not so long ago and failed. My missing game was Menzoberranzan which is much easier to deal with than PoR or CoAB as it was a much newer game. I totally couldn't do it and I decided to stop rather than soil my very fond memories of these games. I think I'd rather try the NWN port again because at least any faults I can blame on NWN or the port than on the source material.

I'll say I'm envious of anyone that can play these again as though it were the first time.
