The Cosmere books are super interesting! I had the Stormlight half last year, and the Mistborn set this year completes the deal. There's a lot to dig into, and some great worldbuilding. Definitely worth owning just to read and plunder from, if nothing else.

And as to that spy game - man, that's super neat. I'm going to add that to my Obsidian vault as something to get familiar with before next summer because I bet my eldest and his friends would go wild with a full summer off and something like that to enjoy! It's the perfect style of game for extended vacations!
