I mean, congrats on the math but is this really something to lose sleep over? lol. Like, yeah, board games are dense, they’re cardboard and plastic in big boxes, so of course they’re gonna stack up heavy. Comparing it to your couch feels like you were just bored at 11pm and needed something to do. Unless your shelf is collapsing, I don’t see the crisis here. You’re probably normal, or at least normal enough, because most people don’t weigh their furniture against their hobbies.
