A board game's awards do not necessarily prove that the game is popular. It could have received awards because judges admired the game's sophistication and design, even if it was not a hit with audiences.
Additionally, these awards are for various categories unrelated to millennials. They might be more interested in niche board games that do not have any awards or are nationally recognized. We should not define millennials' enjoyment of a board game by the number of awards it holds.
