Yea that's exactly it guys, pick the console that has the best games for you. Don't get lost in all the arguments of "well the Xbox is just a media console" as it's all absolute poppycock. The difference in graphics is negligible so don't let that sway your decision. They both look great!
You don't have to have the Kinect plugged in if you don't want to. It is really good though, they have made the games much more interactive like I think I said on one post the other day in Dead Rising you can whistle or shout at the zombies to attract them to you etc. Still feels a bit odd shouting at the tele, but hey it's something a little different. If you want to unplug the Kinect you just pull the wire out the back, it's not hardwired in or anything

it's pretty cool too that you can have your Xbox "always on" in a kind of standy mode so when you walk in the room it just comes on instantly and is like "HEY JAXX!" as the Kinect camera is SO much better it recognizes you every time.
I was sold on a PS4 for ages, then right at the last minute I thought "why am I swaying towards the PS4? Mainly because of reading stuff online with people hating on the Xbox". So then I decided I would stick to what I know and I am happy I did
