Most games these days have short marketing cycles. If you've played The Outer Worlds or Pillars of Eternity, you've got a very good idea of what this game is.
One is a first-person real-time RPG, so if you want to know what it plays like and what the size of that game is, it's The Outer Worlds. If you want to know what kind of fiction and tone it's set in, or what the mechanics of certain spells are, your point of reference is Pillars of Eternity.
