The only large game unique to the German branch of Ravensburger in early 2020 seems to be Jubako, a tile-laying game from Wolfgang Kramer and Michael Kiesling for 2-4 players, ages 8 and up, that's due out in March 2020. Here's an overview:
In Jubako, players try their hand at treat-stacking, trying to fill their own box as skillfully as possible with rice, fish, and various vegetables. The domino-style tokens each show two delicacies and must be placed carefully and stacked even more carefully.
• Another new title from Ravensburger highlights an aspect of German culture with which I was previously unfamiliar:
Spring in eine Pfütze! – Das Brettspiel gives readers a chance to jump in the world of these books, competing in four different task categories — "Gift", "Friend Battle", "Imagine", and "Friend Assessment" — to see who knows their friends well and will use that knowledge to increase their odds of winning.
• Other titles coming from Ravensburger are German-language editions of games previously released in English, with Prospero Hall's Disney Villainous: Böse bis ins Mark (Wicked to the Core) and Ted Alspach's Silver Amulett due out in January 2020, PUSH in February 2020, and Der weiße Hai — the latter two both being from P. Hall — in March 2020.
• You know what wasn't included in the info I received from Ravensburger? News of what's coming from alea in 2020 following the relaunching of the line in 2019 with Las Vegas Royale and an expanded The Castles of Burgundy. I'll be visiting the Ravensburger asap at Spielwarenmesse 2020 to see what's being shown in the booth that might not have been included in press material...
