if you like icewind dale over bg2, then planescape will definitely not be your game. think of reading a novel based mostly on dialouge, with a few puzzles and fight scenes and youve got planescape. its not as long as bg2, but i think its longer than icewind. actually a lot of bg2 features came out of planescape, like noting maps, journal, etc.
