Role-playing video games (RPGs) let you assume the role of a character in a fictional world, making choices that develop that character and shape the story through quests, exploration, and combat, all governed by specific game rules and mechanics like experience points (XP) and skill progression, originating from tabletop games like Dungeons & Dragons. Key elements include deep narrative, character customization, meaningful choices with consequences, and progression systems, whether you're fighting monsters in fantasy or navigating sci-fi settings.
