With Xbox though they are porting a ton of games from the 360 something PS4 probably wouldnt do without charging you.
That's literally what they do lol. They have PS3 games playable on PS4 but it costs you £15 a month. Also you have to stream them, they don't DL to your console and save files don't carry over between them. So when I had a game on PS3, the saves wont work on the PS now version (or the other way round if you decide to actually buy the game)
Yeah but its annoying. I hate having to rebuy stuff I already own.
Plus I want a game to play offline sometimes not have to have a internet connection to stream it.
