Future World - New Game

I have met a lot of people who want PW to do a Sci-fi type game, and I have some suggestions for something like that.

Game name: Future World (or something along those lines)
Premise: Obviously, in the distant future. Good guys(players) vs, Bad Guys(evil robots, perhaps?)
Location: Earth, or another life-sustaining planet
Races: Human, Alien, Robot
Race Description:
Human - After centuries of technological evolution, the Human race has come increasingly far. Technology is at a climax, and is growing more important every day. Humans usually sport personalized mech suits and other technological "niceties."
Alien - A non-human race come from afar to share the planet with the Humans. Little is known about their origin. Aliens have very sleek and lean spaceships and mech suits. Aliens posses energy weapons, which are stronger than conventional ones.
Robot - Highly advanced robotic lifeforms created by Human scientists after centuries of work. These robots are very intelligent and have chosen to ally themselves with the Humans and Aliens in order to stop the ever-growing Evil Robot threat.
Classes:
Human - Mech Pilot, Sniper, etc.
Alien - Energy Swordsman, Energy Gunner, etc.
Robot - Nanite User, Shapeshifter, etc.
Appearance:
Human - Normal Human appearance, armored bodysuit
Alien - Sleek, slender, tall, Black/Purple skin
Robot - Either chunky and tall, or slender and tall

Starting Locations/Main City -
Human - Enrichment/Training Center; Metropolis City
Alien - Travel Shuttle; Mothership
Robot - Programming Center; Cybernetics Base
All Races(similar to Archosaur): Cybrix City

Layout/Gameplay:
The basic layout would be the same as Perfect World International, i.e. the system of NPCs and recieving Missions(Quests).

Flying Rides:
Human - Flying Mech Suit(7/8 ft tall suit that surrounds the player and allows them to fly), Mini-Ship(small, personal flying spaceship/plane), Jetpack(it is what the title describes)
Alien - Artificial Wings(Giant, blackish wings that are purely mechanical), Personal Ship(sleek, long, thin ship that allows for air travel), Gliding Suit(a suit that contains many micro-thrusters that propel the player forward)
Robot - Jet Boots(special boots that allow the player to fly), Transforming(level 1 flying ability, allows the player to transform into a small, clunky flying "ship"), Hoverboard(a long board with anti-gravity engines in the bottom that allow the player to fly)

That is all I can think of for now, the rest is up to any game developers that might use this idea. If this idea is used, I would appreciate some credit.
