Pretty simple. I'm just all around really excited about the system. There's lots of things that I like about it, ranging first and foremost from the games, to the way the OS looks and works, the awesome manner in which Kinect is integrated with the system, and I'm especially excited about free dedicated servers being offered to game developers. That will simply make online games better, specifically the major sports releases I'm interested in such as Fifa and NBA 2K, which makes me feel better about a Live subscription. I don't think the early releases are taking advantage of that, but that's not a big issue.
More specifically.
Games that I want and can't get anywhere else. That's the first and most blatantly obvious thing, and really the top reason.
-- I won't be able to play the next Halo anywhere else, Halo 4 campaign was my favorite in the franchise.
-- Quantum Break is a must have. I never miss any of remedy's games. I don't plan on starting now.
-- Ryse is the new franchise I'm the most excited about at launch. In fact, it's pretty much at the top of my most wanted games at launch list.
-- Dead Rising 3 looks like it's going to be incredibly fun, possibly even the most pure fun launch exclusive. I foresee many hilarious moments being dedicated to this game.
-- Forza Motorsport 5. It fell off my list for a bit, but it's right back on there. I'll probably buy this launch game after I get the others since I'm more excited about the other launch titles, but it's definitely something I see myself picking up.
-- Crimson Dragon is my panzer dragoon game at launch. Not missing it.
-- Killer Instinct looks incredible. In fact, it has been pretty damn surprising in how good it has looked from the outset. No way I see myself not picking this one up.
-- Project Spark. No explanation required. Go watch the videos.
-- Titanfall. Oh, you knew this was going to be in there somewhere, didn't you?
The last two games will be available on PC, too, of course, but I prefer to pick them up for the Xbox One.
My other reasons are simply a combination of features and services that I honestly don't see being offered in the same fashion on any other platform.
I'll grab a PS4 also, possibly early next year, but for now the lineup at launch isn't quite as exciting as what's available for the Xbox One. The primary game that would have likely pushed me to keep my ps4 pre-order was Watch Dogs, and that game was pushed off. It was specifically
the multi-platform release (at launch anyway) that I was most looking forward to comparing between the two systems.
Summary: There's no single reason that I want the Xbox One. It's a number of things, but the biggest draw, if you were looking for one, is the games lineup.
