The people at Black Isle made this for people that want a lot of character developement and story in their RPG's.  Well, they succeeded with flying colors.  You wake up on a mortuary table with no memories.  As the game progresses, you explore Sigil (the city that joins the planes together)and recover your memories and realize that you have some sort of curse of immortality.  On your journey to stop the cycle of dying and coming back, you meet a large assortment of very interesting NPC's that will aid you on your quest.  All of which have pretty deep, well fleshed out personalities and sometimes keep the player entertained with amusing banter with one another.  The game also has a lot of replay value since your choices during conversation and actions you take when interacting with people you meet impact the future choices you'll have.  If you're mean, you'll get a reputation and it will precede you.  The way you assign your scores also makes a big impact.  The higher your wisdom, intelegence and charisma, the more dialogue you will have to choose from.  A higher wisdome and intelegence also grants you speedier recovery of your memories.  So, playing through as a strong fighter will be very different than playing through as a highly intelegent wizard or a smooth-talking rogue.  Ultimately, probably the best RPG I've ever played.
