Sony’s PlayStation console games are mostly focused on stand-alone adventures, i.e. single-player format. As such, they are quite successful, but they do not bring long-term earnings because they do not have a constant influx of new content on which players would spend money and return to those games. Xbox, on the other hand, has games like Minecraft and Sea of Thieves that have millions of active users every month who play them for years after launch.
It is clear that Sony wants its horse for this race and this has been shown by the investment of 3.6 million in the creators of Destiny, the development team of Bungie. And that their live service format is definitely in the plan was confirmed yesterday by a financial report where it was said that by 2026 they plan to launch more than ten live service games.
As a rule, this refers to multiplayer games, but not necessarily. Many live service games can be played mostly on their own - for example, the successful Genshin Impact or the already mentioned Destiny. Ubisoft will say that Assassin’s Creed Valhalla is also a live service game without any multiplayer component.
What’s likely is that these Sony games probably won’t be exclusive to PlayStation consoles. For the success of live service games, it is important to have as much availability as possible, ie as large a base of players as possible. It is for this reason that the most successful titles of this type are also available on almost all platforms.
