I'm upset with my wife about PUBG
Why are you upset at your wife over a video game?
I want to spend time with my wife, and she's always playing pubg, despite the amount of arguments we've had concerning the subject.
If you are upset about her playing games you should tell her. You cannot fix a problem if she does not want to continue to work on your relationship.
Also, sometimes I like the game myself. I would like to play with her.
Playing together might be a great way to spend time together. People need to learn control and limit themselves to their hobbies, especially if it begins to get in the way of their relationships and other responsibilities. It sounds like you need to have a long talk with her about this and figure out what needs to be done if you want to save your relationship.
