The Expanse: Osiris Reborn, a role-playing game similar to Mass Effect, has recruited David Gaider, the original lead writer of BioWare's Dragon Age series.

Background: A BioWare Writer’s Return to a Mass Effect-Shaped Space Opera

The Expanse: Osiris Reborn has drawn comparisons to Mass Effect because it appears to carry forward some of the qualities that made that role-playing series recognizable. That comparison becomes more pointed with the news that David Gaider is collaborating on its narrative.

Gaider is best known as the lead writer on Dragon Age: Origins, Dragon Age 2 and Dragon Age: Inquisition, and is often credited as the architect of Thedas, the dark fantasy world of that series. Mass Effect is BioWare’s other hugely famous role-playing series, which gives Gaider’s involvement an extra layer of significance for players watching space opera RPGs return to prominence.

His career after BioWare included founding Summerfall Studios, whose recent release is Stray Gods, an ambitious role-playing musical. That background matters for readers of The Expanse: Osiris Reborn because Gaider is not simply attached to another sci-fi game; he is a writer associated with large-scale role-playing storytelling, now helping shape a project that sounds like it wants to revive parts of BioWare’s old formula.

Development: Gaider’s Statement and Owlcat’s Fan Response

Gaider said on BlueSky that he has been working with Owlcat Games on The Expanse: Osiris Reborn while continuing his own projects at Summerfall. He described the collaboration as focused on certain aspects of the game’s narrative and called The Expanse one of his favourite series, saying he jumped at the chance to be involved.

The statement is useful because it clarifies the nature of his participation. Gaider is not presented as replacing the development team or taking over the whole story. Instead, he is collaborating on selected narrative areas, which suggests Owlcat may be seeking help on particular character, plot, or worldbuilding elements rather than outsourcing the project’s writing entirely.

Gaider also highlighted the studio’s responsiveness to fans. According to Gaider, Owlcat recast the male version of the protagonist after feedback, reworking and redesigning the Martian Captain. The role is now voiced by Blythe Melin.

This gives readers a concrete example of how The Expanse: Osiris Reborn’s development may be changing in response to public reaction. It also links the collaboration to an official voice-acting update trailer and a visibly revised male protagonist, showing that the game’s public-facing identity is still being shaped.

Latest Progress: Exodus, BioWare Veterans, and Preview Concerns

The Expanse: Osiris Reborn should not be confused with Exodus, another upcoming role-playing game described as very Mass Effect-like and coming out next year. Both projects have BioWare veterans involved, a detail that becomes more notable because the famed developer, BioWare, was shut down and had its own promising, actual Mass Effect game cancelled.

For players, that context makes The Expanse: Osiris Reborn feel part of a broader wave of projects trying to preserve certain BioWare-era role-playing habits: branching character-driven stories, space-faring settings, and narrative-heavy choices. Gaider’s involvement strengthens that impression, even though the game is based on The Expanse rather than a Mass Effect property.

Eurogamer’s The Expanse preview, written by Bertie, said the previewer enjoyed what he played of the upcoming game but raised concerns about the developer’s use of generative AI. That note keeps the project’s narrative promise and its production questions visible in the same view. The game’s appeal now rests not only on its familiar role-playing structure and notable collaborators, but also on how Owlcat handles AI use in a narrative-focused release.

As of the reported collaboration, the game remains in an upcoming development stage: Gaider is contributing to parts of its story, Owlcat has changed the male protagonist’s voice and design after feedback, and the broader space-role-playing context includes fan response, veteran participation, and a reported concern about generative AI.
