Probably the best-known and best-loved game by green-loving and F-obsessed designer Friedemann Friese, Power Grid is about networking energy across a map, keeping the lights on in cities and bidding for better power plants while contending with the fluctuating role of resources such as coal, gas and uranium. A super-sized deluxe edition of the modern favourite came out a few years ago, followed by last year’s Power Grid: The Card Game, which does away with the board and focuses on the bidding aspects for a faster play experience.
