What is your favorite game mechanic?
Many games are built with game mechanics designed to greatly facilitate the player, make the play process more time-consuming, or enrich the gameplay.
My personal favorite is automatic pathfinding in open-world or RPG games, which allows you to relax and get a drink of water while you're on the road. Red Dead Redemption 2, for example, uses movie mode to auto-find your way, allowing you to take a break from pressing your running fingers and enjoy the scenery along the way.
So, what is your favorite or most convenient game mechanic/design in a game you've played? Let's talk in the comments section.
