The goal is for poeple to be able to add games from their library, drag the sliders to reflect playtime, and hit the button. We'll match your taste fingerprint against the total pool.
This is an early demo running on my hand-scored library — 20 games I picked as reference points (Crusader Kings III, Civ V, Bannerlord, Divinity, BG3, Disco Elysium, that kind of thing). Search will only find those 20. Add the ones you've actually played, set your real hours, and the engine builds your taste fingerprint from there.
The recommendations come from a separate pool of 25 indie games I've scored by hand. Small batch, on purpose
Real Steam library import is the next thing on the list. For now: try it with what's here, and tell me if the matches feel right or wrong. That's the whole point of this build.
