PUBG is a good and unique ( the time it was launched) game which was based on Battle Royale format, where you get to choose between various modes of participation like solo or team. And all the players play at the real time which makes it even more interesting and easy to participate than earlier existing games. In earlier games, playing in real time was itself a project as you had to request for a space in existing rooms or create your own room and invite your team to play and all this process consumed time. But, with PUBG all this changed, all you have to do is log in and select the mode you want to participate in and all the other work is done by the game.
This being a real-time game you have to constantly keep thinking about new strategies to win and implement your learnings simultaneously while playing.
Over all its a good game if you want to use it for your benefits. But, yes we also have to be equally aware that we don't get addicted to the same. And this addiction can easily be avoided by defining specific exposure period like 30 minutes or 60 minutes at max. This can help you being productive and developing at the same time.
As George Bernard Shaw rightly said -
“We don't stop playing because we grow old; we grow old because we stop playing”.
Games build our Eye-Muscle Co-ordination, Analytical and Critical Thinking Skills and this is scientifically proven.
