You can download any PS4 game included with PlayStation Now, including Steep.I have a few other gripes with the service. Navigating to PlayStation Now through the PlayStation Store, for instance, is hugely inconvenient. If a shortcut doesn't appear on your PlayStation 4 home screen (it didn't on my system), adding it manually isn't straightforward. I would also like the option to boot into PlayStation Now automatically -- bypassing the traditional home screen altogether -- if I decide that the service is my primary way of purchasing and playing games.
PlayStation Now will also end your stream if you've been inactive for too long. I discovered this after pausing Ico and eating dinner partway through a difficult puzzle. The PS2 classic doesn't have an autosave feature, so I was forced to restart the stream and pick up from my last manual save. I understand why Sony does this -- server management is crucial to maintain stream performance -- but it's still annoying.
Should you subscribe to PlayStation Now? If you have a ridiculously fast internet connection and don't own many games, I think it's worth considering. You can always subscribe for a month or two and blitz through the games that interest you the most. It'll be cheaper than buying them individually through even the steepest sales on the PlayStation Store. If you already own some of the games, however, or have a backlog like me -- just play those instead. You can download and enjoy them without any of the technical worries associated with streaming.
It's cheaper for me to stream the Metal Gear Solid HD Collection, for instance, than buy a second-hand PS3.
Similarly, if you spend a good chunk of time playing Fortnite, Apex Legends and other online titles, don't bother. You're already paying for PS Plus and don't have the hours required to extract the true value of PlayStation Now. (You could, I suppose, make the argument for both if you have buckets of money and near-limitless free time.)
If you fully commit to the service, though, there are savings to be had. It's cheaper for me to stream the Metal Gear Solid HD Collection, for instance, than buy a second-hand PS3. You also never have to worry about buyer's remorse or any sense of obligation to finish something you purchased. With a Netflix-style library, you can just put it down and try something else with zero financial repercussions. For PC players, too, it's an affordable way of accessing PS4 exclusives like Bloodborne and Until Dawn.
Still, I wish the library was broader. Twenty bucks is hard to justify if you're only mildly interested in the games it has to offer. I would pay a slightly higher fee, similar to EA's Origin Access Premier, for immediate access to new PlayStation exclusives. Otherwise, I'm happy with my PS Plus subscription and trawling the PlayStation Store for great deals.
