Boys, Be Ambitious is a worker-placement based game with the theme of developing Hokkaido, Japan's most northern island. Each turn, players place their workers on various cities on Hokkaido, and get the resources that the cities produce. However, you can only place on an adjacent city, thus the players move across the map, gathering resources, building buildings and gaining points. However, in order to score highly, you must balance your relationship with the Ainu – Hokkaido's original population. The player with the most points at the end wins.
