If you haven't played Planescape Torment do yourself a favor and do so. Immediately get over the interface and make a fighter character who maxes wisdom, then int, then any leftover points in charisma. Turn the difficulty down if you want, the game isn't about the combat.
Then do yourself a favor and let yourself explore the world, click everything you can, mouse over everything interesting, talk to every NPC, do ALL the side quests, they don't get old. And stop to READ the dialog. Everything about the game is the apex of professional world-building craftsmanship. In that game you are experiencing a work of art from the inside.
