If I buy a game from the PSN Store, etc. I don't have to uninstall it for hours later, it is enough if I reinstall it or oder?
When you install it you will automatically download it again.
So download the game again for 2 hours?
You have to download it again, of course. You don't have a CD from which you can install it. The download virtually replaces the CD.
But if you uninstall it it is gone and has to be downloaded again, just like with a PC.
Yes.
When you uninstall a game it says you delete it and when you want it back you have to download it for hours
You uninstall a game => it is no longer on your data carrier.
you want to install it again? You need the data again…
As a result, you have to download the game again to access the data, otherwise you wouldn't have had to uninstall it - … To save space, for example, or whatever
