To balance narrative depth with gameplay complexity, I begin by defining a core theme that resonates both in story and mechanics, ensuring they enhance each other naturally. I prioritize pacing, weaving narrative moments between action to avoid overwhelming players with either. By designing modular story arcs that can adjust based on progression, I keep players engaged without forcing linear experiences. Finally, I focus on intuitive tutorials that introduce mechanics alongside the story’s unfolding, allowing players to absorb both elements seamlessly, creating a balanced experience that feels both immersive and engaging.

The most crucial element of game design is balance. Players choose to play because they want to interact, whereas viewers watch films because they enjoy observing. If you offer an experience with a strong focus on narrative depth to someone who wants to be part of the designed world, you may fail to engage them. Therefore, narrative depth and gameplay should be balanced to immerse the player and make them feel like they truly belong in that moment. Sometimes it should invite them to listen, and other times, to participate actively.

Simple! In Levels Don't overload both at the start. Distribute the narrative and the complexity of the gameplay across the levels.

It's core of what your game is gonna be. You just don't do that when developing game. If you didn't had this answer before starting development you don't know what you are doing. And no. Asking users what they want is no answer. Do you know any good book or movie when authors went to make surveys what users want?
