Recent sales of the PlayStation 4 put it at 75 million units sold. By comparison, the Xbox One has sold just half that – 35 million units – in the same amount of time. While 35 million is certainly nothing to scoff at, it has shown in recent years that the Xbox has only fallen further behind the PlayStation. There are a lot of reasons for this, and some of them are PlayStation outmaneuvering Xbox, but many are simply Xbox failing to deliver.

The Xbox 360 single-handily brought Microsoft into the spotlight of gaming. Despite the prevalence of issues like the ‘Red Ring of Death’, the 360 sold over 80 million units by 2013. The PlayStation 3 would eventually catch up to the 360, selling nearly as much, but for many years after the launches of the two systems, the 360 was the dominant machine. The 360 had better online capability than PS3, higher graphical standards, exclusives to some of the biggest titles, and it had more titles than the PS3 by far.

The PS3 was more expensive, with fewer titles, and it was worse quality. Microsoft was poised to take the gaming market. Then two things happened. One, in the years since the release of the 360, the PS3 caught up. The PS3 had time to build a catalogue of games, the price went down, and improvements were made with each iteration. Online stores and options evened out for the two systems, and huge titles like Halo and Gears of War were starting to fade from popularity.

However, the biggest problem came from the Xbox One. In the initial announcements for the Xbox One in mid 2013, fans were confused by the system. Poised to crush PlayStation, Microsoft had seemingly gone mad. The new system would require users to be connected to the internet constantly, even for single player games. If the Xbox One would not be connected for over 24 hours, all games would be disabled on the system. But that wasn’t all.

The Xbox One was also rumored to have the ability to watch gamers through the Kinect. If a gamer rented a movie and more than the allotted amount of people were watching that movie, it would charge the user extra or disconnect. The internet went insane, and this GIF fairly well summarized the opinion of the masses.

The trust that Xbox had built over the years of the 360 was immediately dashed, and gamers were disgusted with what Microsoft had become. Even after Microsoft announced changes only months after the initial announcement, the damage had been done. Last year, Microsoft finally killed off the Kinect, one of the agents of its own destruction.

At the launch of the PlayStation 4 and the Xbox One, little separated them. Both units had high end capabilities on par with one another, and the arguments of the past with piles of screenshots showing which system was superior all but evaporated. Xbox One’s first big problem wasn’t that the PlayStation had more exclusives or more games at launch; it was that the Xbox One didn’t have any that anyone cared about.

In the months leading up to the launch of the consoles, the Xbox One simply didn’t have the mega hits that it had with the 360. Coupled with the invasion of privacy and rights that came with the Kinect, gamers saw little reason to stick to the Xbox. As time went on, the gap between the two systems only increased.

The 360 was known as the system of hardcore gamers, a console dominated by multiplayer games, trash talk, and Rockstar hits like Grand Theft Auto. But in the years that would follow, that image would disappear as all those titles became available on both systems. Currently, Microsoft favors connecting the bases of both consoles. They have come out stating that they would be okay with cross-platform support for many titles, but Sony has not made the same statement. Since the PS4 is decimating the Xbox One in exclusives and titles, they have little reason to give in now.

The PS4’s recent exclusives are titles like God of War, Uncharted, Hellblade, Nioh, Nier: Automata, Horizon Zero Dawn, and Bloodborne. By comparison, the Xbox one exclusives still revolve around legacy franchises like Halo and Gears of War.

At the end of the day, a console is only as good as its titles, and PlayStation simply has far more. It was an ironic twist that all of the things that made the Xbox 360 succeed against the PS3 would be the exact things that made the PS4 succeed against the Xbox One. It’s hard to say if that means Sony finally got their act together, or if Microsoft simply screwed up. With the Switch tearing up sales as well, Microsoft should be looking for a new angle to get back into the game. They are going to need it.
