So this is a standard worker placement board game in a D&D skin.
You play one of the shadow lords of water deep and you have agents(your workers) that help you manipulate adventurers into completing quests for you that advance your goals.
Its a neat little game, and it takes about 1-2 hours to play. Despite how bad d&d has turned out when other board games use it as a theme, I would recommend this one. Its actually a really good game, in that it is entertaining for those who don't play RPGs, but its that much more so for those who know anything about d&d and even more so for those who know Waterdeep.
