If bought separately through the Xbox One Games Store, these games would cost $130, so the bundle saves you $20.
Game of Thrones - A Telltale Games Series and Tales From the Borderlands are the newest games in the bunch, both of which recently released their first episodes. Both were also reviewed very well by GameSpot, which gave them an 8/10 and 9/10 respectively.
In fact, all the Telltale games in the collection received high scores from GameSpot, so if the Xbox One is your platform of choice, it's not a bad way to catch up with them. You probably just don't want to play all of them in one sitting.
