I am surprised not more people have talked about the fact that
MGS5
Kingdom Hearts 3
Final Fantasy XV
GTA5
are all on a Microsoft console. Had you told me that during the PS2 days, that Sonys biggest franchises and system sellers would be on another system, I wouldn't have believed it.
I know the CEO of Square-Enix said he wanted his company to go multiplat, a while ago, but still. To me it's massive that they scored these franchises.
Combining it with stuff like Battlefield, Assassins Creed, Call of Duty, Halo. It's pretty big stuff, even if its just sequels!!
edit: I think Infamous is the top dog of the exclusives. I have a hard time thinking the next Halo could be as interesting as how Second Son looked. It looked crazy good.
