The two had been working closely for some time, but now it's fully official. Asmodee has acquired Repos Production and their library of games (Mascarade being one of my personal favorites from them). Not really much more to say, so let's get to the press release.
From the post:
Asmodee announces today the acquisition of Repos Production, a publisher of successful board games. Time’s Up, 7 Wonders, Ca$h ‘n Guns, Concept and Just One, which won the Spiel des Jahres in 2019, highlight Repos Production’s know-how. Sold in several million copies, the games developed and published by Repos Production are aimed at both family audiences and core gamers.
