Expedition is the name of the game. Monolith Soft had already developed a more expansive open world game than Breath of the Wild 2 years prior to the latter's release. Even though I'm only about halfway through the game (just got my first Skell a chapter ago) and the scattered main quest appears to be very arbitrarily detached from the natural flow of gameplay, when it comes to unadulterated reconnaissance of a vast 3D world not a single game I've played beats it to the punch.
