Riverbed Hunt - A Preview Video (GR) by Epitrapaizoume

About Riverbed Hunt, from BoardGameGeek:

Imitating humans in constructing houses and large ships, tritons quickly became a trading folk, and their agricultural villages flourished on the riverbank of Ie. Triton merchants are known for being able to provide extremely rare goods, such as dried starlight kelp seeds from Ie's riverbed. Humans are willing to pay great sums for them, giving the triton merchants the incentive to seek them out, extract and provide to the market. A group of tritons, which the governing order calls “Separatists”, dissatisfied with the commercial policy of their fellow citizens, began protesting, sabotaging the merchants' trade of the sacred to them, kelp seed. Of course, there are those who seek to take advantage of the whole situation and, in secrecy, exploit both sides for their own benefit... Riverbed Hunt is a light strategy deduction board game for 3 to 9 players. Randomly take the role of a Merchant, Separatist, or the Profiteer. This secret role will define your gameplay. During your turn, perform one of your three available actions. Dive to explore river tiles. Swim to move around the river board. Coop or Uncover to reveal river tiles. In addition, you may play an ability card from your hand, to enhance your strategies. Bring items to the surface until one of the win conditions is met. Reveal enough Kelps and the Merchants succeed in growing their trading business with the humans. Reveal enough Logs and the Separatists succeed in blocking this trade! If enough Coins are revealed, the Profiteer managed to deceive everyone about his intentions, for his own profit! -description from the publisher
