Strictly speaking consoles, when you take the big 3 and put all their exclusives together, Nintendo probably leads the pack with the most, both in intellectual property and games featuring that IP. Microsoft SHOULD be in the number 2 spot there or maybe even number 1.
I would think Sony would come in last but this all changes when you just ask someone who they think has the most exclusives. Microsoft doesn’t stick out at all when I try to think about it just off the top of my head. And they should. They bought up more studios over time than most of the other two, if not more than the other two combined. They should own the rights to PLENTY of exclusives, but I can’t name more than like five different IP’s. It gets less if you want me to name ones that are recent.
They should be leading the pack or at least come close to Nintendo. Course, now that they officially own Bethesda, that number has increased. And in more ways than one. Just the Fallout and Elder Scrolls series alone is enough to be swinging all kinds of mud in the face of the other guys, especially when they go exclusive.
And they will go exclusive. Should they? Of course not. But they will. Microsoft needs system sellers. They haven’t had that kind of pull in a long time. Sony has been showing them up time and time again, and they shouldn’t. MS should be wiping the floor with them given all the companies they’ve bought but it just hasn’t happened. Yet. Microsoft WILL go exclusive with some of these titles. They know what they’ve got and it’s the reason they bought them (and other companies) to begin with.
In the meantime, Ubisoft, it’s been 2,763 days since the last Splinter Cell release (non-animated series or guest spot in another game franchise or VR exclusive).
