Because Xbox has always been my preferred gaming machine, even when I owned a PS3. If it's online multiplayer, I buy it on Xbox. I like the controller better and online experience. Same could be said, why would someone buy a PS4 for multiplatform games? It's all about personal preference. Also, if you look at the majority of other people's posts they have listed multiplatform games as well.

Destiny
Witcher
FF
Dragon Age
The Division
Mass Effect
Dying Light
Elderscrolls online
Watchdogs
MGS

A lot more multiplatform games in everyones lists then exclusives.

Because I don't see the X1 as inferior. Yes, the PS4 has more power under the hood but that alone to me wasn't deciding factor of which to buy. Just like the PS3 did over the X360. Eventually once developers get more knowledge of the X1 you'll see more 1080p games. I play BF4 right now and too me the game looks gorgeous. I dont have time to stare at a tree branch and see some jagged edges when I running around lol. Kinect so far has been awesome. Used it for Skype other day as well as Xbox Fitness and did some Insanity, worked excellent. I really like the X1 UI, the smartglass app that works with it from your phone or tablet, and I've just always preferred online game on Xbox. I like exclusives like Halo, Titanfall, Forza, over Infamous, GT7, and the likes.

Like I said, all personal preference. I have no bubbles now lol
