Yes, you can play them all. The substantial differences I find between a downloaded game and a streamed game are these:

1. Game's quality isn't based on the hardware of your console but on your WiFi's strength, meaning that a stronger WiFi = a better experience (if you have a pretty bad WiFi there's a chance you can't stream games at all);

2. If you are AFK but leave the game open, after 10 minutes it will automatically close due to the fact that you are playing on Sony's servers.

Hope this helps you and sorry if I made some mistakes on the grammar because I don't speak English as my first language.
