For over 300 million years, trees have traded nutrients with fungi in a vast underground network. Scientists continue to make new discoveries about this hidden world -- including the fact that some of these nutrients seem to find their way from mature parent trees, through the fungal network, to the trees’ seedlings. Undergrove is a medium-weight 3X game in which you play a Douglas-fir tree building symbiotic relationships with fungi and using them to establish your seedlings. Players explore by adding new mushrooms to a shared forest area, expand by playing new seedlings and roots on those mushrooms, and exploit their relationships with the mushrooms to gain resources. Players then help their seedlings grow into trees by transferring resources through the fungi. At the end of the game, the player who has grown the best set of seedlings with the most valuable symbiotic relationships will win. -description from publisher
