The digital PS5 can only play games bought off the PS Store, whereas the disc PS5 can so both. However, unfortunately, the PS5 doesn't recognise PS3 discs, so whilst you can play PS3 games on the PS5 (I'll let you know how in a sec), you can't use your PS3 discs.

However, there is good news! You CAN play PS3 games on PS5 via the PS Store. They have a catalogue of games available to download. Unfortunately, you'll have to be subscribed to a relevant PS Plus plan for that, though.

You can also play PS4 games (Physical Disc or Digitally) on PS5 too, which is nice. I definitely recommend getting a PS5 and skipping over the PS4 console entirely, but you can still play PS4 games that have previously released, and more good news is that most of them are a low price now.

The PS5 is a good upgrade from the PS4 in terms of hardware, and it's a very smooth experience, though you may be slightly overwhelmed at first, coming from a PS3. I also recommend keeping your PS3, though, as there's only a selection of PS3 games available on the catalogue. But the amount of great games on both PS4 and PS5 will ensure you don't leave your house for a while 😅

Last but not least, if there is a PS4 & PS5 version of a game, buy the PS5 version if you can, upgraded graphics, stability, frame rates, it's just overall better.
