---- Haven't bought a baseball game since mvp and i would love to get back into baseball games (Obviously MLB the show)
=PS4
---- My friend bought an xbox one for christmas and wants me to get one too so we can play together online in college via NHL (have our own club team)
=XB1
---- Favorite games are NHL, Fifa and assassin's creed
=Both
---- I want a console that has the best graphic capability
=PS4. Most likely multiplats are going to look very similar, but PS4 has the stronger hardware
---- I own an ACER X213H. 1080p and i use the monitor for my 360 and macbook. So I'm gonna have the new console on my desk
=Depends on desk space. PS4 is smaller though
---- Not interested in kinect at all, or any other camera whatsoever
=Both
Use both controllers places for a decent amount of time with different games, determine which you like better?
But either way this is a "you" decision as ratedmoney said. Only you can determine order of importance. Though personally, if I could only keep one I would keep the one to play with my friend.
