I've been playing this on Xbox One and I have noticed several bugs and glitches so far.. But, that is very common for a new Battlefield game, especially one that was developed for two console generations. I just ordered a new generation console hoping that this game may run better since it seems like other players have an advantage. I've done this back in 2015-2016 with Battlefield 4. It was just an "okay" game on Xbox 360, but once I made the move to Xbox One, it was a beautiful game.
If you're looking for a flawless game, this is not for you. If you're looking to invest some time into a new game that will progressively improve, give it a try. I assume that most of us playing and leaving terrible reviews are mostly guinea pigs for the developers to improve the game before the kids get it for Christmas or until people save up enough to get it.
Overall, the 5 total hours I may have played I enjoyed maybe 2 hours of playing and the other 3 hours I was either trampled by other players or dealing with such a delay due to my old console. I found it fascinating that they included the Portal where you can play the old Battlefield games, some of which I played very little of. It is disappointing not having a campaign and limited to only three different game modes with 7 maps I believe. I am certain all of that will change with the exception of getting a campaign added. Hopefully these additions and improvements will arrive before the holidays!
