In single-player, the possibilities for how events unfold are determined by someone else, whereas online, you create them yourself; in my opinion, single-player is nonsense, except perhaps for offline tournaments, because campaigns are designed around the Capitol, but to each their own...

When I read a good literary work, I am grateful to its author, who managed to captivate me and transport me to the world described in that work. When I play a good single-player game, I am also grateful to its author, who came up with a way for me to escape from real-life problems and wander through a virtual world.
You say that single-player is nonsense and that campaigns are designed around the Capitol – but try playing a simple game called "life," where you win case after case, and yet the matter doesn't move forward... Usually, those who are unable to create something themselves criticize others.
