I saw some people online saying that they should make a LEGO game based on the entire Infinity Saga, I assume in response to the release of Skywalker Saga and like... it's a cool idea but Skywalker Saga was 9 movies. The Infinity Saga is 22 (amusing you don't include Far From Home because it's the only post endgame film that's technically part of it). Like, that is so much larger of a project it's practically impractical. Especially if you wanna do what Skywalker Saga did and give Equal treatment to each film regardless of that film's quality or relationship with the fan-base.
I don't know. Maybe you do it as two games, or some sort of ongoing release..... but it still seams a little too big to work.
