In Strange Remnants, you and your fellow investigators travel to the haunted ruins of massive stone monuments across the world. You must learn the secrets of these ruins and perform the requisite rituals before the cosmos aligns against you, an evil portal opens in the center of the universe, and the entire Earth is devoured.

This one plays it pretty close to the belt, adding one new Ancient One in Syzygy, a bunch of cards to mix in with your rapidly growing decks, and then some 'Mysteries' and new Adventure cards, which fall in line with the new mechanics in Mountains of Madness. I think this is a good pace, one small box expansion and then a larger one, lets players absorb everything. Excited for Under the Pyramids, the next large box.

Great if you enjoy the base game. Terrible if you don't. More depth and interesting new investigators/spells/assets.

Syzygy is an exciting and interesting addition to the game, however many added in cards and items are very self-referential and do not smoothly integrate into the rest of the game from a mechanical viewpoint.
