Games like Spacebase DF-9

A game is here when it shares the strongest of Spacebase DF-9'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 Spacebase DF-9's own series that play like it stand apart, above the list, and take no place on it. A similar typical length breaks near-ties, and a game sold twice is shown once. A game Steam marks adult-only is listed only for a game that is one too. Games that share the same kinds with Spacebase DF-9 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.

Under each name, how it differs from Spacebase DF-9: a kind of game it is that Spacebase DF-9 is not, a feature its strongest Steam tags carry that Spacebase DF-9's barely do, how many hours people play it beside Spacebase DF-9, and how its reviewers feel beside Spacebase DF-9's.

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 name, the share of its Steam reviewers who recommend it: loved at 90% or more, liked at 80%, mixed at 65%.
