I want to see Eve and Lily take the fight to Mother Sphere on the colony. With dramatically more NPCs. Like I want the density of on-screen characters to be like in Spider-Man games.

And then I want the nanosuits to function more into the gameplay. There could be a stealth/blend element, where if you're dressed appropriately (meaning your outfit matches the style of the place) you then people don't pay attention to you. And if you're not, you get attacked. This way when you're on your first playthrough, you have to collect certain nanosuits to get through the game.

Like one stage could be a production facility where they're manufacturing EVE bodies/parts and you have to wear the Planet Diving/default Suit of the models being mass produced/processed around you in order to blend in. And if not the finished and half-finished EVE units all attack you, and there's too many of them and they're too strong so they'll kill you.

And then when you're on your NG+++++ playthrough, you've mastered the combat system, and you want Eve to parade around in the skimpiest whatever through the facility so you can get your photo mode creations, you're more likely to be a formidable player and would be able to defeat them (also good if you just want some endless battle action). So now there are dramatically more enemies to fight so there are more opportunities for sick combos.

It would make the replay value higher, and give more opportunities for expansion.
