I realized the only game I play online is FFXIV, which doesn't require PS+. I almost never play the "free" games they add to the service, and spend a non-zero amount of time browsing said free games in an effort to find something to play rather than something in my backlog. So I just canceled.
My membership is up in December and I doubt I'll even notice when it's gone.
Price rises aren't welcome and the latest one does seem quite high. However I've been paying for plus since I got my PS4 and I'm still ok with it. Considering I maybe buy one game every two years for the price of another triple A game a year I've built up quite a library. The hours my partner has put into Spiritfarer, Slay the Spire and Hades indicates it's still providing good value. Every month we at least check out the new games unless it's a survival horror.
If I have one complaint it's since I got off the CoD train as I got older when I do occasionally dip into the free ones via plus I find it very hard to find any online matches. I assume this is because all the hardcore players move pretty quickly to the current iteration leaving the lobbies of the older games empty.
Same here, I set to cancel renew every time I top up and since late ps4 time I don't even add free games that are remotely interesting so I keep a cleaner library. And then when they announced the hike, I did the review and filter by games acquired via plus, same feeling, I almost never play those games, even though they look somewhat interesting and added them but probably never gonna play them since my primary interest and good backlog will last me long enough for next main games to release. So they will have the same treatment like my humble bundle games. And I also decide to not top up any more.
