Best Console Deals
Gears of War: Ultimate Edition Bundle (that's 4 games)
Fallout 4 (and Fallout 3 code next week) (that's 2 more games)
think this one is completely sold out.
Both Tomb Raiders. (2 games)
1 TB HD (standard is 500 GB).
Xbox Live Gold
Buy 1 month for $1 from within the console. Then buy 12 month for ~$30 via CDKeys. Don't buy Xbox Live Gold monthly at $10/month.
Gold is necessary for online play and you get up to 4 free games per month. You need to go buy Xbox Live Gold.
If you like EA's many games: Dragon Age, Battlefield, Titanfall, PvZ, Need for Speed, and their endless line of sports games. Then pop down $30/year for EA Access all-you-can-eat pass.
Multiple special controllers on sale.
Standard console comes with 500GB. This is not enough. But Xbox One can use up to two more external harddrives at once. I prefer 2TB Western Digital or Seagate portable harddrives - they can draw power from the XB1 directly and you don't need an extra plug. Because of XB1's Hyper-V setup, external HD actually runs faster than internal HD. These are regularly around US$65 and dropping.
I buy Digital.
There's extra discounts if you are an Xbox Live Gold member, which is $1 for this month.
Kinect, TV Tuner
If you are on the edge about whether you need these, pass. They have their place and I love them, but Black Friday is about awesome deals and you can skip these.
