Can anyone provide a link with accurate information to how the DRM/trade-ins/lending etc works? seems all a bit of a mess and no one really knows at the moment!
As you don't seem to be getting a straight answer from anyone else, here you go:
You can trade in your games at authorised retailers. Publishers may decide to charge a fee (to the retailer or the customer) for this service (so basically no more online passes as they can charge this way instead if they wish).
You can also gift your game to a friend. That friend must have been on your Xbox Live friends list for more than 30 days. A game can only be gifted once (your friend cannot gift the game to someone else afterwards, though he/she can trade it in).
If your machine is offline for more than 24 hours, your games won't work until you log back in to Live. The console needs to 'check-in' to verify that you still own the games (i.e. you haven't traded them in or gifted them).
You can play your Xbox One game on any Xbox One console in the world, provided you are signed on to your Xbox One account. If you don't have the disk, you can download the game from the store.
You can install games to your Xbox One's HDD and play disk-free (essentially what most of the above is in place to allow - you can't have disk-free play without DRM).
Currently there isn't a solution in place for renting games or lending them out to friends. This might happen in time for launch, or it might not.
There will be a solution in place at launch to allow families to share games uninhibited across multiple Xbox One consoles. Details on this system haven't yet been announced.
So, advantages and disadvantages versus the current system (and the one the PS4 uses):
Advantages
- Disks no longer needed
- Can play anywhere, anytime - games can be downloaded to any console and will come complete with your saves, allowing you to pick up where you left off
- Instant switching between games and other disk-based media (e.g. Blu-Ray, DVD, CD).
Disadvantages
- Trade-ins via authorised resellers only
- Selling on forums like this can only be done using the 'Gifting' system (with the restrictions that brings)
- The console needs a reliable internet connection - if your internet goes down for more than 24 hours, you can't play your games
- There's currently no system in place for renting games (e.g. from Lovefilm, Blockbuster etc.)
- You cannot (currently) lend a game to a friend. You can play together on your friend's Xbox One, but he/she can't play on his/her own without buying the game.
It's very much a mixed bag. If you currently use GAME for trade-ins, don't rent games and aren't prone to lending them out to friends, it isn't really going to matter (so long as your internet connection is reliable). Unfortunately, there's enough negatives that a lot of people can find something to grumble about.
To me personally, it doesn't matter so much. I don't rent games, I have no issues with using authorised resellers for trade-ins and swapping games with friends is a rarity. It's only the 24 hour check-in requirement that bothers me. The thing that's turning me off the Xbox One isn't the DRM, it's the price. Given how many of these games are coming to PC as well, it's difficult to justify spending £430 on a new Xbox. With pre-E3 rumours of Fable IV, Banjo Kazooie and Beyond Good and Evil 2, I'm a little disappointed in the games line-up too. Lots of 1st/3rd person shooters and action games with little else.
