Sins of a Solar Empire®: Rebellion

Worth buying? What 300 Steam reviews say.

Very Positive · 94%2012

The verdict

A deep, slow real-time space strategy with huge fleet battles and a legendary mod scene. Skip it if you need a campaign, a modern UI or smooth late-game performance.

Great for

Players who like slow, deliberate space strategy, big fleet battles and modded Star Wars, Trek or Halo games

Main risk

No campaign and an overwhelming, dated UI, so the learning curve can feel punishing
