If you regularly use a PS5 or PS4, there's very little reason not to be using PS Stars. This rewards programme, currently only accessible via the PlayStation mobile app, rewards users with points for PS Store purchases, as well as neat little digital collectibles for completing simple campaigns. Part of the service also allows you to use your accrued points to redeem PS Store credit and, if you have enough, entire games and other digital goodies. It's these PS Stars rewards that have recently been refreshed, and there's some good stuff up for grabs — if you have the points.
In terms of full games, you can now spend points on the likes of Rise of the Ronin (17,500 points), Helldivers 2 (10,000 points), Minecraft (5,000 points), and Balatro (3,750 points). These join a handful of titles that have been in the rewards section for longer, such as GRIS, Stardew Valley, and Dredge. That's a pretty great selection of software, though you'll need a good number of points saved up for some of those more premium games.
The rewards go beyond that, though; there are also several premium currency packs available to redeem for PS Stars points, for games like Gran Turismo 7, Genshin Impact, Destiny 2, and more. You can claim some DLC too, such as Bloodborne: The Old Hunters and Cuphead: The Delicious Last Course.
