What Does "Role" Mean in His/Her Game? (Need Context)

I need more information to answer this. "Role" depends entirely on the specific game and context.

Please clarify:

• Board Game / Tabletop RPG? (e.g., "What is the role of the Banker in Monopoly?" or "What is the Cleric's role in D&D?")
• Video Game? (e.g., "What is the Tank's role in Overwatch?" or "What role does Mario play in the story?")
• Social / Party Game? (e.g., "What is the Spy's role in Spyfall?")
• Game Development? (e.g., "What is the Game Designer's role?")

Reply with the game title and the specific character, class, or position you're asking about, and I'll give you a detailed answer.
