I didn't play Planescape Torment when it originally released. My excuse? I was about five years old and more interested in eating grass or something. But I played the Enhanced Edition that released in 2017, and instantly realized why this game is considered a classic in certain circles. However, the game never received any official DLC. Despite this (or maybe due to this), fans have taken it upon themselves to create Blizzard in Baator, a full DLC that restores cut content from the original game, and adds a brand new region.
