Why are RPGs addictive?

Why is it that Role-Playing Games, or RPGs, have such a strong hold on players, often leading to addiction? Could it be the immersive storytelling that transports players to fantastical worlds and allows them to live out their wildest dreams? Or is it the sense of accomplishment that comes with completing quests and leveling up characters? Is it the social aspect, where players can connect with others from all over the world and form tight-knit communities? Or perhaps it's a combination of all these factors that makes RPGs so irresistible? I'm curious to know your thoughts on this topic.
