I remember the question, it wasn't about E3 but someone asking about his personal opinion on the future of MS studios. Which is why I bring up the fact that Shinobi's opinion is going to depend on story based games being an interest for Microsoft. That's more than likely why his says diversity in the lineup is important not quantity, he probably see's a lot of multiplayer, GAAS or all around not story focused games in development. You have seen the way Shinobi has responded to some publishers like Ubisoft moving away from story based games.
But with success in this generation with a decent amount of third/first party story based games or single player campaigns. Is it hard to fathom that people are sick of multiplayer being the main driving force behind a games creation or project status?
Microsoft double down on GAAS with franchises and developers who have no experience making them ala SCALEBOUND, FABLE LEGENDS. In the case of fable they were in a sense shut down on a awesome sounding fable 4 for a game that they had no clue how to market, make and monetize.
Shinobi is not alone there is a Mod here named MH Williams who I think is also a writer for a publication or website and made an article on gameindustry.biz about MS state of software.
And it was pretty much the sentiment of shinobi among others as me and Sneakers.
IT'S not just Shinobi's outlook it's a lot of peoples and has to do with all around excitement about what Xbox has, and people already have a giant list of online games they can play to take up their time.
Xbox has a big deficeit issue with diversity in software, mainly in games that are not online focused.
