It depends on how the servers are run.
Will it be private servers or just public servers.
Every PC game has the chance for hacks but hacking isn't as rife as people think - PUBG is meant to be one of the worse games for hacking, and I have only played the game and been killed by a hacker about 6/7 times in the hundreds of games I have played.
I will most likely buy the game when it is released, but they will have to price it competitively, especially during Early Access.
It would also have to do something special with the PC market full of MMO games and good ones.
