Cornertone has already won two major awards; the 2009 Mensa Select Award and the Parents’ Choice Silver Honor. Cornerstone Essential is the newest game by Good Company Games. Game play is just like the original Cornerstone, but the Cornerstone Essential version has been specially designed for faster play. There’s now an added twist of strategy, forcing players to build even more carefully, because the foundation they set up at the bottom will help make or break their success at the top.
