Despite being a broad genre, one common aspect of role-playing games is how they give players the chance to make their own choices. Often, these choices exist within the narrative, with many RPGs including mechanics such as social simulation, branching narratives, and morality systems. Additionally, class creation and choice can have a huge impact depending on the game, making the ability to create a personal character incredibly important, whether that involves distributing ability points, choosing classes, or creating a build from scratch.
