It looks like PS Now training for September 2021 has begun to leak, though we haven’t been able to corroborate the story, so you may keep your expectations under control until the offer is officially announced on Monday, September 6th. The selection is quite wide and starts with Final Fantasy VII (the original version), as previously announced.
Here is the full schedule, as reported by PlayStation Portal:
This month’s poster, if accurate, is surely supported by smaller, more interesting independent experiences, though we highly recommend Moonlighter if you haven’t played it yet. We will check with the owner of the platform and try to get some kind of confirmation about this selection and update it as soon as we know more. In the meantime, you can find it All PS Now games through the link.
