The idea is that Neverwinter will add a game-within-a-game, allowing characters in the MMO to sit down and engage in some good ol' fashion tabletop D&D: "Respen's Marvelous Game takes place atop a table, with your character being transformed into a miniature statuette. This new event will challenge you on a whole new level. Now you will know what it is like to be on the other side of a tabletop game!"
Of course, this is just a joke. Or is it? Cryptic teased the possibility of earning a green slime companion and said that it will be revealing more details tomorrow.
