It's up to you, It's still pretty early and might be better to wait for a price drop as even tho I have had my xbone for just over a month now I still think lots of things need improving, also you really do need a fast internet connection and perhaps uncapped.
I am going to tell you that Sunset Overdrive is just another TPS so if you don't mind another one then get it.
Anyway I am somewhat enjoying Sunset over drive mostly for that garish cartoony style. This is my vid below of multi player, the final challenge is a tower defense. The good thing about these current gen consoles is they allow you to record your gameplay and upload to a site like youtube. It is a little fidly so you need to set it in advance otherwise you might lose your team objective because of it.
