As of now, Sony offers two membership services: PlayStation Plus and PlayStation Now.

According to a new report, Sony plans to unveil Spartacus, it's equivalent to Xbox Game Pass, "as soon as" next week. The previous speculation suggests that Spartacus could be a hybrid of PlayStation Plus and PlayStation Now, two of Sony's current subscription services. While the service is expected to include a number of well-known titles, it may not include the upcoming God of War: Ragnarok.

There will likely be three tiers to the service, each with a distinct set of games and correspondingly varying prices. Following that will be tiered that include PS4 and PS5 games (though those will only be available "in the future" according to report), "access to extended demos and the option to stream games over the internet," and other perks. A collection of older titles from systems like the PS2 and PSP may also be included in the highest tier, according to previous reports.

As of now, Sony offers two membership services: PlayStation Plus (which includes multiplayer gaming, discounts, and a few free games each month) and PlayStation Now (which includes select PS4/PS3/PS2 games through cloud gaming or download) (which options are available depending on the specific title).

These services are pale in comparison to Xbox Game Pass, which lets you play big Xbox and PC games the day they come out, as well as a selection of third-party titles.

Although reports indicate that Sony's new Spartacus service will rely heavily on the PlayStation's enormous back library rather than today's hottest new releases, the company appears to be aiming for a service that PlayStation customers can get enthused about.

It is also unknown how much it will cost. When purchasing an annual subscription, PlayStation Now and PlayStation Plus currently cost $60 per year each, for a total of $120. That's around the same as the normal Game Pass subscription and a little less than Game Pass Ultimate, indicating that Sony has some pricing wriggle room.

There is also the problem of migration – you can purchase many months, or even years, of PlayStation Plus subscriptions. It's not clear how Sony plans to handle users who aren't on a month-to-month contract. Spartacus appears to have a fairly comparable tier, however, there could always be price changes that need to be taken into account.
