We bought the XBoxOne last year and it does everything we need and more. Great graphics, speed, really fun.
If you're not a gamer (I'm not like some guys) you can have a lot of fun with Madden, and sports games.
But if you want to have a great time, get "Fallout". In fact, I'd start with Fallout 3, then go to Fallout New Vegas and then get the latest one. We haven't gotten Fallout 4 yet (but I expect my son will be addressing that on his list to Santa...and he's 18).
Other good game: Call of Duty , Black Ops
