I really enjoys A Short Hike, which contains a combination of loops and arcs. The main interaction loop that improves the player’s skill is generally moving around, such as climbing, flying, and running, while throughout the game there is the main arc of getting to the top of the mountain (which requires the player to be proficient at climbing and other movement methods) as well as separate mini-arcs through NPC interactions, such as retrieving a camping permit that was eaten by a fish.
