Update: Publisher Stardock has clarified that Sins of a Solar Empire 2 is an "ongoing service" rather than an early access game now. This does feel a bit like a matter of semantics, though, given that the Advent faction is still to come and the game is yet to be put in the hands of reviewers. Stardock CEO Brad Wardell notes, however, that the goal was to leave early access when it had as much or more content than the original game at launch—a milestone he says was achieved last year.
"Our goal on Epic was to release Sins of a Solar Empire 2 1.0 with the same or more content as the original release of Sins of a Solar Empire 1.0," says Wardell. "Once we hit that milestone in early 2023, we turned off the early access flag and began working on what amounts to Sins of a Solar Empire: Rebellion feature/content parity which we will reach this summer and is the version being released onto Steam and as part of a massive free update for Epic users. We are aware that most people who have played Sins of a Solar Empire think of Sins of a Solar Empire: Rebellion as the definitive version which is why we have waited until we had reached that level of content to begin our larger public awareness campaign."
