Looks like it could easily be my favorite game if they execute it well, love the expanse and very much want more of it after the show ended before finishing the books.
Reminder for beltalowda: Telltale, as it rose from its grave, the first game they released upon returning from the dead was "The Expanse: A Telltale Series", a prequel story about Drummer (who is voiced by Cara Gee).
It's unfortunately only available on Steam and Epic Games Store on PC and not GOG.
And until I know more about Osiris Reborn, I'm imagining it a bit like Mass Effect based on the description, "story-driven action RPG".
