The price is Steam's US list price for the game by itself: not a sale price, a bundle or what anyone paid. The hours are the ones its reviewers had played, not a time to beat. Its kind (idle games) is what the game is first, as a model that knows games named it once from a list of Steam's kinds (for a game it did not know, its strongest Steam tags name it), among the kinds with at least 20 priced games here; failing that, by its Steam genre. The going rate is the middle hourly cost of those games, and the receipt prices its typical hours at it. The words beside it compare it with its kind: loved is 90% recommending it or more, liked 80%, mixed 65%; it gets played when a quarter fewer of the owners read here never launched it than of its kind's typical game. Whether it holds up is drawn on the hours road above, and counts toward the one-word answer.
