The concept of pubg was absolutely different and graphics are also so good but no that much that anyone waste that much Data and space of its phone.
The game have many draw backs like if you have started at once then you cant pause it for a while, if you lost your net connection for a moment than you definitely going to lose it.
Many amendments can be done in its controls like range of firing, enemy detector etc.
There are many games which give much more enjoyment in less data than pubg.And the strategy need is very much less.The games should be have qualities which nourish the thinking power, reaction abilities and concentration power of a gamer.The game lack in all this.i will suggest other good games in less data like COC, counter strike, The free fire etc
