It was something I have thought about and wondered for a while now, and the answer is yes: you can fit the base game, both expansions, the extra map and all sorts of stuff you printed from the web into the Memoir ’44 box. It isn’t a perfect fit, but everything goes in the box and the lid stays closed, so I count it as a success. Now I just need some medium-sized ziploc bags to keep the armies separated and small bags to sort the tokens and it’s perfect.
