The one thing I am enjoying so far is the very fast load times. Have not bought ACV or Watchdogs (though I do want to at some point) been playing mostly Destiny 2 and some other older games. The load time reduction makes playing so much more enjoyable.
Also put in grounded which seems much better as well, Smoother and better looking? (maybe my imagination).. but again load times... wow.. did not think this would matter so much to me.. but it does.
Next will be trying out Wasteland 3, gave that up because.. I did not like load times between zones.
Now I have to decide, do I sell my XB1X for like 250 (Canadian) or keep it for my bedroom (most likely) or.. trade it for a PS4Pro so I can play some of them exclusives like Spiderman
