Third-Party Power
Third-party developers have had a huge part to play in this generation, and while they’ve not always remained impartial, the number of developers releasing their titles across all systems (though sometimes after a timed-exclusivity deal) has certainly led to a blending of the console experiences.
After all, some of the biggest and best games each year come from third-party developers and release on the major systems at the same time. Sure, Microsoft, Sony, and Nintendo will always offer their own exclusive experiences, but these make up a small chunk of each system’s library. As such, players across all platforms are, for the most part, getting the same experiences. It may run a tiny bit smoother on one system over another, but these differences are often so marginal you’d hardly be able to notice. And there’s certainly no need to “war” over that.
