NFS 2015 can be played in single player mode, but annoyingly it requires an internet connection.I used to buy games on xbox gold in the 360 days, then my console got banned so I couldn't play those games online anymore. Ever since then I stopped buying downloaded games and would only buy second hand dvd/blueray ones from game. I do have some original PC/PS1/PS2/PSP/PS3/PSVita games and some OG xbox/360 games and 1 switch game - but I stopped buying games a few years ago now and I only pirate for the exact reason that most new games need online activation/patches and extra downloads to work properly and many are not even at a proper release state when released so you are forced to go online to get a patch. The fact that these companies servers go ofline so often and they can pull your paid content at any point doesn't inspire me to part with my money anymore so I will stick to piracy from now on.
And GT7 when it's offline it plays like a demo whereas if you're connected to the internet you get the full game.
This should be illegal.
