Heroes of Land, Air & Sea is a RTS inspired big box game. That features 4X game play. It breaks the mold of regular 4X games in that it is easy to learn, simple to play, and games only last 2 hours. It is a Scott Almes design after all, designer of the Tiny Epic series. Gamelyn Games mandates their products only be sold in your brick & mortar store, or through a website you own.
