Now that you realize how one can play digital games offline on your PS4, go ahead and enjoy your whole digital purchases without worrying that they're going to all of the sudden lock in case your internet goes down or if there's a PSN challenge. Your PS4 may already be your main system, but still doesn’t allow you to play games offline. As with the anime, the inventive crew's most important goal was to let the player "really feel" Lain, and "to understand her issues, and to love her". This could fix the issue and allow you to play your digital PS4 games offline on your primary PS4. You bought them, so why cannot you access them each online and offline? Note that you have to be logged in to PSN to access this and thus should have an web connection. So, you should be on-line to play your digital games in order that Sony can confirm that you've got the license to play that game. Your major PS4 caches your licenses, so you won't need to be online for Sony to verify them.
