Steam knows what you own, not what you played
Steam's library lists every game you've bought through Valve, tracks playtime, and surfaces recent activity. What it doesn't capture: your intent (backlog), your status (currently playing, finished, dropped), or your personal opinion (your own 1-10 rating, separate from the public review). Dungeon Logbook fills exactly that gap — it's the layer on top of ownership that tells the story of how you actually play.
