Security 51: how long it is, and whether it holds up

How this list is made

A game is here when it shares the strongest of Security 51's Steam community tags, Steam genres and IGDB themes, each shared tag counting for more the fewer games carry it: two metroidvanias are alike, two action games barely. Games of the same series come first, a similar typical length breaks near-ties, and a game sold twice is shown once. Games that share the same kinds with Security 51 stand together, under those kinds. Up to 30 games are shown, and the list stops where they grow much less alike. Where to start: the closest; the best loved of the closest fifteen with 10,000 reviews or more; the shortest of the ones 80% or more recommend; and a hidden gem, 90% or more but under 10,000 reviews.

The sticker on a case is the hours its own page leads with: half of the game's Steam reviewers had played that long or less when they gave their verdict. It is not a time to beat. Under a case, the share of its Steam reviewers who recommend it: loved at 90% or more, liked at 80%, mixed at 65%.
