While Microsoft has done away with its "daily check-in" requirement for the Xbox One, that's not the end of strange new digital firsts for the system. Witness Forza 5, which even when you buy it on disc, needs to download more of the game online the first time you fire it up.
Sounds crazy, but Turn 10's Dan Greenawalt tells IGN that there's actually a fairly sensible reason behind it:
So when you first boot up the game, we’re going to ask you to log in. And when you log in you’re going to get the Drivatars and you’re also going to get a whole bunch of content: tracks and cars. Our production schedule is such that we are putting them in as late as possible and that means making them free as downloadable content on Day One.
Before you say "but that's just DLC", nope, you need to get online and download this before it'll let you play the game (though remember, with both new consoles you'll be able to play while you're downloading).
The days of a video game ever being "finished" are well and truly behind us, folks.
