Quote: "The game will take place in an apocalyptic place. The genre will be similar to Bf2 and Stalker. Characters will have outfits on like radiation suits. And maybe some of it will take place in space. I want the game to take place in different climates, snow, sandy, and more. The guns will be modern. I want the enemy to be a Communist army formed from places like China, Russia, and Cuba. That's what I got so far. So I need a good story for it all. That's what I'm having trouble with."
thats something to handle with. thought of the main character? what was his profession before the war? family-guy or lonewolf? wich job he has now or what abilities to (fly) around the world fighting in ww3? secret agent, soldier, smuggler (!), freelancer,an escaping deserter who sees no sence in that war, a father in search for his family/son-soldier.... depends on your preference only. make a profile for the mainchar first, then you will get further ideas, especially to wich places he goes mainly depends on this. a janitor from ohio wont travel to arabian dessert in most cases if he is not a soldier or in search for something.
while "soldier in a postapocalyptic war" is used about a million times, try to find something else would be nice, even to get better ideas for something unique.

äähm, there is only 1 communists country left in the world, and thats north-korea, and even they will open the gates the next 5 years... ok, 1 1/2 when thinking of cuba too, atm.

to call a country like china comunistic that has buyed into half of the us-companies using the capital markets to do this over the last decade is... misplaced.^^
but it gets political wich isnt allowed (hard to find a realistic global story without discussing these things^^).
