PUBG is probably one of the best Early Access games I have tried. It can be fun, but it can be frustrating as well! Unfortunately, their Battleye isn't functioning properly, so you can run into hackers, which I have done a few times already.
The lag in the beginning in the game can be very annoying, when you just landed with the parachute, which can course early death.
You should get higher rewards depending on which rank you get. I've experienced only get 140 credits for being on rank 2, which is really not anything.
But overall, I think the game can be fun.
I will recommend to play with 1-3 friends.
