Thanks for the video! Legendary Marvel is one of my favorite games; I also play with the Golden Solo rules. Though I've never done a final showdown. Instead, I like to see if I can beat the Mastermind a fifth time (though I'll still take the win if I don't quite get there!). I agree that Dark City is a good expansion to add. The base game was intended to be played COMPETITIVELY. It was almost assumed you'd beat the Mastermind-and whoever has the most points wins. If you play the base game like that, it still works. But if you want a challenging co-op/solo experience, you need Masterminds from the expansions.
I saw that too when I was looking around, to just fight for a fifth time, and it was something I was interested in as well! When we do this co-op, I think for sure we'd like the competitive part because even when working together, it's nice to know who pulled their weight at the end of it haha
