Is it possible that Sony backed SFV to compete against Xbox One’s fighting game juggernaut, Killer Instinct?
Author’s note: This article is purely my opinion and conjecture, and is not based in fact. I am a fan of both SF and KI, and this article is simply for creating a discussion.

Street Fighter 5 launched in 2016, and is widely considered a misstep for the hugely popular franchise. This article explains why that is.
Every Street Fighter is called a misstep of the series since Street Fighter III..and even the Alpha games were not liked by everyone.
SF V had a miserable start but later it did a lot things actually better than SFIV and SF6.
SF6 is the first SF since SFII Turbo for that I did not buy at launch. And today, around 6 months after its launch I still have no motivation to buy it.
I grew out of fighting games, loved them as a kid but online you just get your ass kicked over and over leaving just the bare bones single player and also having no friends anymore who like fighting games either just makes me not want to buy or play them anymore.

Street Fighter documentary 'Here Comes a New Challenger' is now available for all, following a successful crowd funding campaign.

Round One: FIGHT!!
Nah, I dont think Sony thought about Killer Instinct at all when they made this deal. It was probably just for the PS4 to have a major presence at fighting game tournaments, which are becoming a big thing in esports
Street Fighter is the best fighting game in the industry by miles and Killer Instict cannot even come close
Lol Killer Instinct is not something you need an answer to. Sony is just locking down the FGC and Street Fighter is the biggest fighting game franchise.
I'm pretty sure Sony wanted to be engrossed in the Tournament scene. What better way to do that then grab up the biggest series in the Tournament scene.
Considering the history and scope of both games in respect of personal and tournament usage, I'd think the SF deal was based upon the formidable fan base of SF rather than the existence/exclusivity of KI.
