Playing Pandemic Legacy S1 with my Wife (we did three meeples between the two of us, one representing our daughter who’s only like 1) was one of the most rewarding co-operative experiences I’ve played. I’ve always wondered whether anyone would try doing a ‘digital’ legacy game, but then digital games in general are, in their own way, ‘legacy’ games because of the way the game world can evolve through your actions (thanks to the magic of software).
Actually taking the cardboard legacy systems (which are influenced by the restrictions imposed by physical components), would be interesting to see at any rate. You could make it tied to a specific save… like how two playthoughs of a Paradox Grand Strategy game are never the same. So in one save you made this choice, and that choice… and the game ends up being like A. And another save other things happen and you get the B state, and so on…
I guess the danger is, how many potential outcomes can you design into a game via choice, and what happens when you’ve explored them all?
I own Charterstone put haven’t started playing it yet. The way it was described to be was that the ‘legacy’ bit has you building your semi-custom worker placement game, and at the end you have your own unique game that you can play infinitely (just without any more legacy choices to make). The Aeon’s End legacy game is similar, from what I understand.
