Great idea, bad implementation.

Which each new update the game was slower and slower. At first they promised to optimize the game, but nothing happened on this aspect, on the contrary: the game was even worse.
Instead of optimizing the game they keep releasing new maps and old skins with different colors and higher price.
Pro players with 2080 Ti were complaining about the frame drop after updates.
Bugs fixed in one version resurfaced in later versions, regression testing anyone? Like dropping below ground and you can't get out, couldn't pick the items from the ground, couldn't reload the weapons, clicking to shoot somebody is not registered you had to change weapons in order to work. From this point of view they look like rookies in programming.

They need to fix the desync - you find yourself knocked/killed a few seconds after the shooting ends and you are behind a wall/building. In the past during fights the game froze and the message "Network lag detected" was displayed and you were dead after the game unfroze. It happened even during "Face it" a LAN competition, they can't blame the network lag the problem is in their network code.
They need to do something about the cheaters, right now they're just pretending. They ban a cheater, the cheater makes another account and he's back in the game. PUBG Co is making money and the honest player accumulates frustration and stops playing the game. Not to say about people with KDA below 1 permanently banned without reason and they don't have to give you an explanation for ban. They even closed the forums because people complained about bugs, cheaters and unjustified bans. So much for transparency. Sometimes you could find fixes for crashes and other issues on their forum. Most of the time when the game crashed I had to reboot the computer.

I don't see myself paying for another game made by the same company, maybe except if they release the game on Linux, but that's not going to happen because of the anticheat application, which is useless IMO, which doesn't work on Linux.
If a cheater use radar on a different computer the anti cheat app can't detect it.

I've played the PUBG mobile and the PUBG Lite versions too, they are a cheating fest, especially the lite version. If you want to be killed by flying boats go play the lite version. It's fun at first, but the fun doesn't last long.

The game is not dead yet because of the pandemic.
