The BIS dudes gets some kind of advanced and highly effective anti-ageing treatment and still making great games. LoL..
The game would be called OFP Galaxy or ARMA galaxy and would probably run thru a new console that has a sort of wii-like device that can be transformed into the form of a gun. and monitors are replaced totally with Virtual Reality goggles. You are really in the game's environment now.
As OFP Galaxy would go intergalactic It would be a new theatre of war. Countries would have colonized other planets, moons, asteroids, and have built bases and space stations. New weapons and new tactics have to be developed or would have been developed. There'd be jumps from planet to planet using spacecrafts or even spaceports and stuff. Battles on moons, space stations, fortresses or even free space with space infantry wearing special gear for such environment. Not to mention, it would basically cover all known types of terrain and environments. Space, land, underwater, ice, desert, volcanoes, black holes, etc..
And it would take an immense amount of programming work to put that together. The variation of physics in the different environments, mapping of entire planet systems and even stars and constellations, and editing would be even more a headache than before. the AI would be so advanced that it may even think a waypoint assigned to it to be unsound and decides to take a different course of action altogether. LoL!
Ey, enough, enough... don't listen to me.. i'm crazy. hehehe!!
