A game where you get to make giant monsters on an editor similar to spore. You could then make special powers for your monster and classify it in a certain group. You could then create a city based on your liking on a similar editor, so you could make a gloomy cloudy big city, or a coastal village. City size would be chosen by the player. If you wanted you wouldn't have to make a city, and you could just live in an ocean trench, a volcano or other similar environment. You would control the monster and either become a dreaded threat, a savior, or be worshiped. You could then visit procedurally generated versions of other players cities. You can encounter player created monsters and either fight them, join them in attacking the city, or help defend their city. I am not sure what you would upgrade with a monster, but powers are probably the main choice.
I think this game would be tough to make, but I would buy it. If it did exist I would make a gigantic silver-blue bird-like reptile similar to an archeopteryx. It would spew a high powered silverish white ray of ultra-cooled breath that erodes at an enemies body or buildings. It could lower temperatures as it flies overhead. It could also create ice shards by flapping its wings.
What kinds of monsters would the rest of you make and what challenges do you think would be if Maxis tried to make this game.
I had an idea like this once, but you would just pick a location on the planet instead of creating one, it would be with cryptids instead of monsters, and you would get points for keeping your cryptid well hidden, killing other cryptids and animals, etc. One of my ideas was a crow-like creature that lives in New York City, and the only difference between it and a crow would be that the cryptid could fly at supersonic speeds and is able to shoot a sonic sonic blast from it's mouth.
