By price
Price divided by median reviewer playtime — how much you pay per hour of gameplay. Lower is better. Reviewers tend to sink more hours in than the average owner, so treat this as an optimistic estimate. Free games are excluded because there's no price to divide by.

How the math works: we sample each game’s Steam reviewers, take the median of their total recorded playtime (lifetime hours, not hours at the time of review), and divide it by the game’s current price in your selected currency. Reviewers usually sink more hours in than the average owner, so the numbers run generous. Free games aren’t listed because there’s no price to divide by, and a game needs playtime data from at least 20 reviewers before it qualifies. All prices are Steam’s own regional prices, never exchange-rate conversions.
