Wouldn't surprise me if that will be the real case for the next game. xD

A post-apocalyptic war game would be really cool. 

I was thinking future warfare, like between worlds and space, but I'd take that as well. :D

Kojimas next game is gonna be like a action packed Snatchers

Its fells that futuristic warfare has been overused so much this gen. I would expect Kojima to do something out fo the norm.

A Kojima work so could make sense.

Well, it isn't like the post-apocalyptic scenario is any fresher either, doesn't it?

Since there are mechas in his new game, you can bet it's war related. I wish it was more Gundam than WW2 tho.

Or maybe WW2 fought with Mechas. :P

I don't know if going open world was the best decision. I mean Metal Gear V did great sales and critically wise, but I feel that the plot suffered from lack of timing and direction.

I wouldn't mind if his next project develops in a more controlled environment.

I don't know what he has on mind right now. The only thing we can be certain about, is that it will be a real Kojima Game

If an already artistic vision in Kojima's mind made him/them decide which path to go: open or more linear, than I suppose they could choose between the two options taking into consideration the two following factors:

- budget: how ambitious they could be with the world they are creating

- how successful the latest approach to MGS with MGSV has been and relative positive critical reception
