Ok, so as a DM I love making an immersive world and giving detail that encourages the mindset that the PCs are important in the grand scheme of things only after a certain point. Just like there are npcs that are weaker than them, there are greater characters than them as well that they cannot yet compete with. Just like there are some encounters that are super easy there are others where they really should have considered running. But my Players often have none of that.
More than once several of them have told me explicitly that this is a power fantasy for them, they are the heroes, and if they are not the ones solving the problem or if there is an encounter too big for them that it is my fault for not presenting a level-appropriate encounter. Long-story-short, they want an action movie. The stakes are high and if they are not the movers and shakers, why are they not instead playing the movers and shakers? I feel like I'm playing a game about a complex layered world of which they are only one small part, their influence growing larger with time, roleplay, and levels, and they are playing a video game where they are the chosen ones, or at least the epic heroes, and everyone else is there to support them, reward them, ply them with plot hooks, or be defeated by them. They even use video game terms like "optimized strategy", "dps", and "fetch-quest" to refer to actual named story references. I hate this feeling, but these are my friends and I want to continue playing with them. Has anyone here successfully handled this before?
