Rogues of Manhattan-Awesome Game Idea

I came up with an awesome game idea out of nowhere. Actually an awesome game series. It sucks i could never pull it off but ima post mah ideas


Rogues of Manhattan---------
Not much backstory but the general outline. An advanced Alien race took over the world with there technology. The sky over the US and surruonding areas is blocked because of the Aliens massive mothership and smaller Alien battleships hover over key points in continients
A Alien battleship hovers over the White House where the Alien General who rules over the US, named Markeen, resides. Markeen likes entertainment so he announces that every US state will have to assemble there own army and battle each other. The winning state will be allowed to co-exist with the aliens. However, one man from the New York Manhattan army is tired of the conflict. He starts a rebellion and soon recruits others to there cause. His name is Leo. they call themselves the Rogues of Manhattan. Leo and his comrades stumble onto a secret base in Virginia where a large group of scientists form every state are building cruisers to combat the aliens. They are scronging alien junk to make it. Eventually the cruisers get running and Leo and the rogues go to combat the battle cruiser. While the rest of the now army assaults the ship, Leo infiltrates it and battles Markeen. Markeen is defeated and the alien engineers set the ship to explode and destroy North America in its entirety. Leo exits the ship in his custom ship and for a final boss, destroys the ship, liberating the United States from the Alien threat, but the aliens still rule the world.
