Hello.

The other games from the developer, Journey and Abzu, have similarly free movement, though the levels are more linear. AER Memories of Old and Sable, if I remember correctly. Shadow of the Colossus could be considered somehow like The Pathless - open space, enjoyable traversal, but it is available only on consoles. There are also Prototype and Saints Row IV, but they are action-adventures with very different settings and tones.

I would not recommend Lost Ember or Spirit of the North, despite some surface-level similarities.

This reminds me on Fe to some extent.

would recommend ABZU and AER Memories of Old for similar games. both are chill experiences and a bit shorter with good replay ability in my opinion. plus in Aer you get to turn into the bird

Sky: Children of the light is free and it is a similar game. Main *story* is great, after that its mostly a boring grind but the main game is fantastic.
