I think it’s very important to keep new players updated on what to buy taking into account the current status of reprints. It’s a situation that fluctuates greatly over time, so the 10+ year-old content that I find about Memoir '44 needs continued validation from players.
BoardGames4K just published a new video where they leave out most of the stuff that is long out of print, like the campaign books, but delves a bit deep into the buying order for the expansions, which I found interesting since the order didn’t really match my own.
In my case I played through the original scenarios and after realizing how much I liked it and getting Mediterranean Theater as a gift, I got the Winter Desert board and then Eastern Front, Winter Wars and the Terrain Pack. I finally caved in and got the New Flight Plan after that.
