What if... you stop making threads with no sense or logic behind them?

This would happen:

Well after several years of legal battles and infighting over management they would break apart.

I don't even want to think about it...

That would mean no SquareEnix or Capcom games for me anymore. I boycott all of them

well and KingDigital never heard of that before.

Finally a release date of kingdom hearts 3 and final fantasy xv.

King Digital is through makers of Candy Cruah Saga, BTW.

scary thought. thats a bunch of suck in one place, it might cause a black hole.

Then we'd get a First person assassin RPG with beat'em up elements in boss battles in which you eat candy to regain MP or HP :)

The answer here? Well, it's a bit complicated:
Activision will stop its mobile efforts and focus more on mature console titles. Expect this to become an FPS/Action-Adventure house.
EA will most likely take hold of the more casual/mainstream console/PC franchises from the other publishers. Even then, they can milk Maxis and the annualized sports franchises.
Capcom will most likely keep benefiting from being the Fighting game house, and they still have MonHun to milk.
Ubisoft will have its niches eaten and then some by Activision and EA. I think they'll downscale to being a good publisher - more niche titles, less hype. Friendliest to Nintendo platforms.
King will be the most obvious beneficiary in this case. The mobile efforts will be shunted onto them, guaranteeing them a revenue stream as long as the rest exist.

Verdict: This is a conglomerate that is enough to launch its own gaming hardware. End of story.
