Long time lurker, first time poster.
Just before WRPG turned to what they are today (action-RPGs for most part, not that I find that bad per se), there was golden era that lasted for quite some time of turned based cRPGs made by Western developers. From that era (I really don't want to go to "once upon a time in C64 and Amiga land" here) my absolute favorite (though both Baldur's Gate and Fallout 1 are close behind) is Planescape Torment - with rich story, memorable characters, interesting puzzles and pause based combat, this is something that kept me coming back to it for more than a decade.
