It's all digital
We've popped open a copy of the Forza Horizon Limited Collector's Edition so that you can peek inside for yourself. While the casing is nice (a steelbook and slip case), the innards of this package aren't much to look at as all the goods are digital.
With each Limited Ed. you'll get a shiny ticket with three codes that unlocks a VIP membership and accompanying car pack, a day 1 add-on pack, 5 more car pack liveries, and an accelerator token pack that will give access to new cars, maps and other goodies. So there's a sh*tton of content that comes with this $79.99 edition, though it doesn't look like much in the unboxing video.
Forza Horizon is in stores now.
