Sony recently made the very wise decision of allowing for a subscription plan for PlayStation Now, letting you play over 100 games on the service unlimited every month, as long as you paid $20; with the move to the subscription plan, a free trial that is typical of all streaming services has also now been made available- Sony is now offering free trials for PlayStation Now on the PSN Store.
The service requires you to download the official app (just a couple of megabytes), and to be living in the US (no, not even Canada is currently supported). Once you sign up for it, you can use PS Now for free on any supported device (PS3, PS4, PS Vita, and PS TV) for seven days, after which point, your card will be automatically charged for a month’s worth.
So if you wanted to see what the service is like and how it would work with your connection? This free trial is a great thing.
