when you get the xbox one...use upload studio to go watch other ppl play the game that way you can see if you like the game...there are a lot of games in the game section
but since you have a ps4 already you probably already have all the multiplats on that so if I were you I would look at
PVZ (second best game on either system) you already have titanfall DR3 (there is a demo for this to try it out) Ryse zoo tycoon (there is a demo for you to try it out) Kinect sports rivals (there is also a demo for this) Crimson Dragon Peggle 2 Powerstar Golf (been hearing good things about this game)
How has nobody mentioned Killer Instinct yet?! Definitely worth getting. TitanFall is already covered. I've heard good things about Plants vs Zombies and Dead Rising 3, just haven't played them yet myself. Crimson Dragon isn't that bad, but sadly I hardly got too far into it. it just got lost in the shuffle for me.
