A combination CTM Survival map, Catharsis is sort of the minecraft equivalent of The Phantom Tollbooth 
This is actually a very enjoyable map. The locations are excellent and the map maker has done a fine job of taking the ‘catharsis’ theme and making it come to life in the many cavernous rooms the player finds him or herself in. The map is so large it almost counts as an adventure map, to be quite honest. It’s missing some elements of story, but there is a narrator that follows you throughout your journey and playing this map really does feel like going on a journey. Catharsis is definitely one of the Must Play Minecraft Maps for January 2013.
