Metro Exodus is a “story-driven” linear open-world experience
Quality over quantity you could say, as a smaller arena within which to murder everything with a digital pulse can provide a more concentrated experience. By the sounds of things, that’s the direction that upcoming on-rails (heh) shooter Metro Exodus is aiming for. All the strengths of a game which very much knows which direction it wants to move players in, with the chance to deviate outside of those parameters if players feel like doing so.
