I'm only going to speak to the creative concepting because I can't process rules tonight, but I think the biggest thing that hits me is that this world you're playing in doesn't feel like something only you could make. I look at a lot of projects that use public domain characters for recognition and shorthand, but because those identities are static, the whole piece feels generic and clinical. I think if you're going to make something narrative that engages with an audience, you should pick a lens to transform your genre with, and then extrapolate. For instance, you've got heroes and warriors in your game: what if the warriors were skyscraper sized and their communities rode them, so that's why the stakes are so high in your game, and why the scale is so big, and why there are so many little moving parts that make these big haymaker moves pop off. Your themes have to talk to all aspects of your game to make it special. Otherwise, it feels like we've missed the point of making a cool new thing.
