The opposite of linear video games, non-linear video games are video games with a free-form system of progression. This includes sandbox and open-world games. A non-linear game or path is when a game lets the player affect where they go next. The path branches out, like a tree. Players have a choice of where to go, or what to do, next. Non-linear games are favoured in certain genres like role-playing video games.
