Assuming you pay for the service and spring for the more expensive PS3 controller, that's still $50 - cheaper than a brand new copy of a AAA game these days. The controller can be a little dicey (Ps4 controllers still run about $60 for a new one) but you're able to use even older PS3 controllers, which cost $15-$30 depending on if you spring for an offbrand or Sony controller. If you've got a PSN account from any former PlayStation products, like the PS3, you can use those or make a new one.
If you want to test out PS Now, there's a 7 day free trial, but after that it's going to be a $19.99 monthly fee, albeit for a library of games and not only Bloodborne. RELATED: Rumor: Bloodborne Leak For PS5 And PC Resurfaces Online
You'll need a compatible controller, but for people who don't have a PS4 and want to play Bloodborne, this is a way to do it for much cheaper than going out and buying the whole $300 console. What a lot of people don't know is that thanks to the oft-forgotten PS Now, you actually can play Bloodborne on your PC, and have been able to do so since the game was added to the subscription game streaming service two years ago in 2018.
