It's possible to own a PS4 and not have a subscription to PlayStation Plus, but if you're a serious gamer, you're unlikely to be satisfied with that arrangement.
For many people, the best part of having a PS4 is multiplayer gaming, and you need a PlayStation Plus subscription to be able to do that. But in addition to PlayStation Plus, there's also PlayStation Now.
Now, you might be wondering if you need both, so here's a breakdown of what's in both subscription packages, and what they cost.
While you get certain elements of the PlayStation Network for free by virtue of owning a PS4, like access to entertainment apps and the ability to watch content on PlayStation Video, most of the valuable features are only included in a subscription to PlayStation Plus.
That includes the ability to play multiplayer games online, access to free games each month - which, once downloaded, you can continue to play for as long as you have a subscription - and exclusive early access to game demos and betas.
PlayStation Plus also features 10GB of online storage for saved game files.
There are several different subscription options for PlayStation Plus:
PlayStation Now has some elements in common with PlayStation Plus, but it's really a very different kind of service.
While the main selling point of PlayStation Plus is multiplayer gaming, you can think of PlayStation Now as more of a Netflix for games - it's a subscription-based streaming service that lets you play any number of games from Sony's substantial library of PlayStation titles, including older PlayStation consoles, for a single price.
You can stream the games to your PS4, Windows PC, or a number of other devices.
