There's a genre of game that doesn't get enough attention — and it's quietly becoming one of the best ways to spend an evening. Murder mystery case file games hand you a stack of documents — police reports, witness statements, forensic analysis, photographs — and ask you to figure out who did it. No board. No dice. No app telling you what to do next. Just you, the evidence, and whatever conclusions you can draw from the details. If you've never tried one, you're missing out.
