Planescape has returned to Dungeons & Dragons. Planescape: Adventures in the Multiverse includes three new books: the setting book Sigil and the Outlands; Turn of Fortune’s Wheel, the campaign book; and Morte’s Planar Parade, the bestiary.
Magic: The Gathering has been going hard on the brand crossovers through its “Universes Beyond” line this year with the likes of Doctor Who and Lord of the Rings.
