In some ways, Memoir '44 is the game that birthed SU&SD. Paul and Quinns were playing a long campaign of this definitive game of toy soldiers when they decided to create a board game web series. Historians can find our ye olde review of Memoir right here (timestamp 15:01), filmed on a borrowed camcorder on a sweltering summer's evening.
A more recent Memoir video we did is our Operation Overlord Let's Play. While Memoir's campaign books make it a longer game and the Breakthrough rules are there if you want to make it more tactical, Overlord is what you get if you want an epic experience.
If only all games could be tailored to the same extent! What a world that would be.
