Best Space Sim indie games under $20
These are the best space sim indie games you can buy for under $20. indielist lists 8 paid space sim games with a list price at or below $20, ranked by Steam review count so the most-validated picks lead. The average list price here is $15.87, and the cheapest is Fractal Block World at $6.99. The most reviewed is Dyson Sphere Program with 82,685 Steam reviews. Beyond the budget end, this wider list adds 6 mid-price picks between $10 and $20 that a stricter under-$10 list leaves out. Every price is the tracked Steam list price, not an estimate, and each game links to a white-box sales estimate you can open and audit rather than a black-box number. This is a value list: a sensible price crossed with real player validation, so you can find a space sim game that is actually good, not just affordable. Free-to-play titles are excluded here; this is about paid games that punch above their price.
