I only get PSNow when one of these two conditions are met:
1) I have nothing to play, need something to play ASAP but can't decide what to buy.
2) I want a game that I'm uncertain of if I'll like it but it's on PSNow.
3) The rotation has one or more games in interested in playing. E.g. When they put control and Shadow of the Tomb Raider in, I paid for that month and beat both games.
I don't care for day one as I rather support the developers I like or if the devs have done a great job. Surely they make more from actual sales than gamepass or PSNow.
If a game that wasn't on my radar turns out to be amazing e.g I couldn't stand turn based jrpgs so I tried P5 in PSNow and then purchased it on PSN store.
And now with digital sales being so frigging cheap, I rather just buy the game and keep it in my library.
