Not all open-world games are RPGs. These titles prove exploration, creativity, and action can shine without leveling systems or stats.
The main story of the base game leads everyone to feel like a passenger in the main plot, but this isn't the case in the Shivering Isles. Players play a major role in the plot, help a doomed deity escape their fate, and can potentially assume their role as Sheogorath, the Daedric Prince of Madness, which is as impactful as it gets.
