I will talk about the gameplay. I am not gonna tell bugs or problems. So read If you wonder what you will be doing in game incase you buy it.

First it is exciting and your own survival challange begins, it goes like that for the first few hours finding food, clothes, some tools and an axe if you are lucky. So after all if you fed yourself well and not thirsty your survival goal kinda ends. Maybe from now on you want to see some bigger, nicer cities. You run all the way to another city and when you arrive you can slightly see other people or you can keep scavenging houses. But mostly you will find more food, more drinks and more clothes. Finding a firearm is one thing and finding bullets for it? Only if you are lucky. Also you will need a magazine too.

Lets think you have rifle and pistol and full magazines with you; you are well fed...
What is next?
Kill zombies with your axe by one hit, don't bother wasting ammo.
Zombies are not very large groups only 2 at the same time mostly, so zombies are not a treat too.

Will you keep scavenging till you have 3x of everything? No. Since you got nothing better to do you start to kill other players. If he is lucky you can shout freeze, capture him, put on handcuffs and give him a chance to live maybe. If you don't think that way (most players do not) shoot him from behind and take his all scavenged items at once. His hours are lost now.

But its not that easy, you will run a lot to find firearms in military bases first (which those bases are mostly far away from your spawn points), than you will run some extra more to go back to crowded cities where you can hunt people. And 2 hours of doing that, you die in 2 seconds. Nonsense! That guy did the same thing he wasted his 2 hours. And you guys shot eachother. Now if you want to live that 2 seconds or try to not die this quick next time go ahead waste another 2 hours of your life.

Will I keep playing it? Yes. Because I love it? No. I paid for it.
