Forza 5 won't include all of the game content on the Blu-ray, you'll need to download content before you play
Next-gen gaming is upon us, and it is a weird world we're about to step into. With Forza 5, you'll need to download game content from the Internet before you can buy the game. Yes, even after you've inserted your Blu-ray copy of the game into your console.
Turn 10's Dan Greenawalt, when speaking with IGN, explained that there is actually a good reason behind this: "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."
So it's not technically DLC, because it's part of the game. I'm kind of on the fence about this, what about those with slow Internet connections? But, it means you get up-to-date content, which is a nice touch. It also gives developers a few extra days to do some last minute changes to the content, which hopefully means we get less issues, and better games.
