I am very impressed by both the game mechanism, and Sage Games’ digital version. Moderately steep learning curve, with a good payoff—it could be an introduction to worker placement games, which is a genre. I found it more accessible than iOS Caylus. Not quite as slick as Carcassonne, Pandemic, and (I hear) Agricola, Lords of Waterdeep. But it gets the job done, and it is usually cheaper. The font on the cards should be bigger. On iPad Air, I still require squinting.
