VG Sci Fi Overload

so I have been dreaming of the greatest movie-scifi game ever......Imagine a metropolitan city in the present time... now imagine a game engine that has a sandbox enviorment. Now imagine all the sci worlds merge into a nexus of alternate realities right into this city.

Now you play the main character living a ordinary life in this city (you happen to be ex black ops and are a weapons expert of all kinds, plus a skilled fighter piolit).

The world is free form so you can do whatever you want. The first part of the game you run around the world and learn to play and explore. There is an air force base, office building etc. At one point you are approached by the men in black. (Now I don't want to use any main characters from any of these universes so it wouldn't be K and J, maybe S and T or something) They tell you that you we are not alone in the universe. And you can start doing missions for them. As the game progress the sci fi worlds start merging more and more into your world.

Aliens invade the streets, good thing you killed a predator and took some of his weapons. You find a warehouse full of face huggers..

The Independence day aliens mothership hovers over the city. You drive to the Air Force Base in a MIB car that you have now cause you did lots of missions for them. Hijack(borrow) an F-22 and take out the mother ship)

Enterprise E is in orbit around the planet. The borg are attacking.. Do enough quests for the away team and you can beam up to the ship and help defeat the borg. Maybe you have to take the Defiant and attack a cube.

Dr. Who steps out of the T.A.R.D.I.S. on the city streets, because the Darleks are invading.-- This would be the last mission since the Darleks are probably the biggest threat of any sci fi alien ever.

Light sabers heck yeah. Maybe a bunch of stormtroopers need to be taken care of. Grab an X-wing and see if you can't see whats going on in space. Take out some Tie Fighters.

Then the rest of the game would have little extras from other scifi worlds. The monolith from 2001 would be up somewhere... The Dune sand worms might come out from under the streets. Maybe you pick up a ghostbuster proton pack and trap. War of the World aliens are annoying so you need to make sure to have some biological warfare weapons. A T-1000 comes out and is trying to kill you. You find some of the planet of the apes in the local zoo. Godzilla comes out of the water.

-Good stuff. Greatest Sci Fi game ever.
