A friend of mine just shared this on Facebook. Here's his succinct, accurate, and headdesk-worthy summation:

"- If you wish to give a game to your friend, you can only give a game to someone who has been on your friend list in the last 30 days, and the game can only be given once.
- Third party publishers may opt in or out of supporting game resale and may set up business terms or transfer fees with retailers.
- No renting or loaning of games are allowed at this time.
- If your account is accessed on a different Xbox One, you will need to pass an online authentication every hour, rather than 24 hours.
- A broadband connection is apparently required, as Microsoft has stated the following: "because every Xbox One owner has a broadband connection, developers can create massive, persistent worlds that evolve even when you’re not playing."

After talking to a friend of mine about what PS Plus offers, I am a) incredibly jealous in the short term, and b) really excited in the long term. For anyone who plans to make a smartass comment about "well, why would anyone own a 360/why didn't you buy a PS3 to begin with," first, please go slam your head in a door. Now that that's over with: because Sony didn't offer any of this shit until they came under new management (PS Plus didn't exist until midway through 2010) — until fairly recently in the overall console lifespan of this generation, Sony was NOT at all kind to its customers. Such was the state of affairs when I actually got a console from this generation, at any rate (some time around 2006) — and not all of us have enough disposable income to switch game systems mid-stream.
