I have played a lot of hours in this game, not exactly all are played as I have left the game running idle for many hours or forgot to close it. I wish Steam tracked "active" hours versus just sitting there paused, but anyway that is a rant for another time.

Here are some of my pros and cons to the game as it currently stands from a long time player:

Pros
Highly Customizable Goals/Objectives
You can make this game be anything you want. If you want to be a survival versus zombies you can do that, if you want it to be survival versus other players you can do that! If you want to RP as a survivor in the PZ world you can do that. The options are endless!!
Realistic Thought/Activities
You can drive vehicles in the game, and while driving you can't craft. Jumping through broken windows can injure you. These are things you should know/expect to happen when performing them and it is a lot of fun to see this implemented.
Mod Support
Countless mods to add whatever you want in the game that doesn't come wrapped with the vanilla product. If you want to fight zombies with a large spoon, guess what, there is a mod for it. There has never been a time that someone has asked "Is this in the game?" and my response, "There is a mod for it" has failed.
Learning Curve Is Steep - Base Game
This game has a massive learning curve, and I thrive on that so it is a personal pro for me, but not everyone wants to do that. But again, it is highly customizable so I find this as just an added feature from the base game having such a learning curve.
Great Price
Very affordable for what it offers and I would challenge any other company to make the same type of game and charge the same amount. I have been a gamer for over 30 years, and I haven't seen it. However, if someone knows one I would love to learn about it.

Cons:
End-Game Is Very Limited
While I mentioned it as a plus that you can have some highly customizable goals/objectives, once those are accomplished the game doesn't offer much. You have to accept that basically there is no end-game/roll credit scenario, the ending is up to you and sometimes the race to complete your goals might not take very long. This is a problem of all survival games in one sense or another, but it is a problem of the genre versus this game in particular I feel.
Critical Bugs/RNG
Some people will experience bugs that will end their game and it isn't their fault. I have seen screenshots and experienced issues where my character just up and died while walking down a set of stairs before. This has happened on MP a lot, some of my friends die from desync issues. This is something the dev team is aware of and working on in regards to MP, but these are problems you could encounter. RNG can also stack against you, you might be looking for supplies and hop into an alarmed building after being injured. You might find a cool weapon right off the bad or not find one for many days making you struggle tremendously. RNG is a major factor in encountering the bugs as well.
Update Roll-Outs
The game is developed by a small team, and so they are slow at making updates. Not everyone has the money to throw around like some big AAA companies, TIS is very much an Indie Company and so they don't have crazy resources so expect slow delays. Some people are impatient, and I can be at times but it is a fact of life you will encounter.

These are my thoughts from a long time player, I love playing this game and I enjoy hearing others having fun with it as well. It is a game that can be really great to play because of the elements and things you can do in it. However, expect some issues that may or may not end your game too early that is not your fault.
