For an extreme example, Eve Online is a game that makes kids do feats in spreadsheets that set them up straight for careers in accounting and supply chain management.
But less extreme: if your game exposes numbers, spreadsheets are useful to play with them. If I knew more about Excel when I was 13, I'd probably retype unit stats from StarCraft into it and do the maths that I ended up doing in my head. Spreadsheets have plotting functions, which are a fun thing to play with. Also tracking my own magazines & CDs is something I remember doing as a kid - entirely doable in Excel, though in my case, this was my first exposure to Access and RDBMSes in general.
Also worth noting that a proper spreadsheet like Excel is in itself a functional reactive programming REPL. FRP is what you do when you play with formulas.
Spreadsheets are a great visual way of programming up to a certain point.
Spreadsheets are great for maths, planning projects, tracking experiments/collecting data, ... which I'd also all attribute to things "STEM-ish kids" might do.
