Power grid is a fascinating look into the power generation industry with a rather lovely game driven energy source market which sets the price of the different raw materials you can use. As the game develops better and more efficient energy plants come into play and are sold in an auction situation, as well as that each plant requires certian raw materials to operate (except the solar driven plants). It's a game of balance and hand management with the goal being the first person to connect up a number of cities. The two sided board offers a large number of possibilities for playing the game so you shouldn't tire of power grid very easily.
