but I am still holding my decision of Icewind Dale vs Planescape Torment s Neverwinter Nights.
Just buy and play Baldur's Gate 2. It's quite possibly the greatest rpg ever made. It has a good mix of varied combat encounters, decent story, and great character interactions.
It isn't essential to have played BG1.
Planescape is a great game, but a bit more dated in some ways (graphics and interface), and also more subject to specific taste (very text heavy). IWD is decent fun in its own right (I like the sort of combat shared by the games), but as an actual rpg it's far inferior to PS:T and BG2.
Like I said, I'll be waiting until BG2 enhanced edition.
