Can I download a game to ps4 from my friend's account and play? What should I need to know before doingit? Can I get banned from psn? Can I play it from my account after downloading?
I will try give a understanding here:PS4 A - yours (in your house)PS4 B - friend's (in his/her house)You, log in PS4 A, but PS4 A is not your primary device. This means, you can play your games bought from PSN, as long as you log in as this account.You, then log in PS4 B, your friends, and activate his/her PS4 as your primary. This means, he/she now can play your PSN games you bought from his/her account.When you go back to your house, and you log in again in PS4 A, your account in PS4 B won't be deleted, but will be logged out from PS4 B. Your friend still can play your PSN games (because primary account PS4 can access all master's library).There's a real drawback here for you because you activate your primary PS4 in PS4 B: You can't download games by using computer to your PS4 A (trigger remote download) because you claim that your PS4 is PS4 B. This will instead causing PS4 B download the game you buy, not the PS4 A.Your PS+ auto-upload features (only auto-upload) can't be activated in PS4 A, because your "designated primary PS4" is PS4 B. You still can manually upload your save data to cloud storage from PS4 A, but this is a hassle.Then there you go if you want to "share" your games with your friend.
Can I play games on ps4 without internet?
Thanks for the A2A by Sai Mukund R!Yes! And no.. Kind of, games which are purely online. E.g. Overwatch, you can open. Click ‘X’ and then it says fetching online profile. Cancels, and that's it.. however, there are loads of games where you can play without internet. To name a few FIFA, COD, BattleField, (however this series is much much more enjoyable online). But you can still play them.You can play games offline, campaign or local.You can also, take screenshots and record gameplay. However do note, you cannot live-stream or upload your records, or screenshots, without an internet connection.Hope this helps.EDIT: Some games, such as COD mentioned in Asad’s answer do require a certain amount of updates to play. Like if you tried it just straight away with it updates, it wouldn't work. Or you'd get a very limited game.
Do we require a Playstation Plus account to play FIFA 18 on a PS4, with friends?
Unfortunately yes you need Playstation plus and Xbox Live Gold to play online on the respective consoles.
What is the idea of game sharing on a PS4? Why do people do it? Is it legal?
Think of share play like having a buddy over and you play a game with local multilayer , you're player 1 and they're player 2. You're both playing the game on your system. Now share play makes this same experience possible through the internet. You're player 1 and they're player 2, you're both playing the game on your system. See it's exactly the same but with less fighting over who has the P1 controller because you're always P1 but you can “give” them P1 control if you're stuck on a singleplayer game.It wouldn't be mass distributed if it were illegal
