This is an awesome game. It's not too complicated to learn how to play, but the challenge is real. There are also a lot of mods to add to the game to make things slightly different, or to make it even a completely different game (overhauls).
It's fun to play with friends and everyone can specialize in a skill class, like farming, scavenging, hunting, fighting, mining and so on. In the end you need all the skills to survive.
The crafting possibilities are quite good. You can make your own base in an existing facility or from scratch, in different shapes and you can even paint everything the way you like. There are vehicles to be able to get around faster. There are different weapons and clothes to choose from with different perks and levels, which also can be modded. The more days pass by, the better your loot will get and you'll get better armor and weapons, but also the zombies will get stronger and harder to kill.

If you like story based games where you really get into the story and get connected with the characters, this is the game you need to get. At first personally I found it hard to get a grip of the controls and how everything worked, but after only a few hours of playing it have gotten very intense.
