Don't Starve Together is a multiplayer roguelike survival game with horror elements. It has a very stylistic macabre artstyle, with gameplay that hinges on a deep and varied crafting system.
Pro Pleasantly twisted sense of humor
There's a dark sense of humor that pervades the game. There's a humanoid spider boy who can grow a beard of silk. There's a living chest called Chester who acts like a dog. There's also silly info text, werepigs, trees that retaliate when you chop them, and many other things.
Pro Deep and varied crafting system
The crafting system has a lot of depth to it and there are tons of items to make. Starting with the recipe for a torch and a pickaxe. You can also make weapons, armor, and various laboratories that enable new technologies. Building new stuff and advancing is the key to surviving the coming winter.
Pro The further you get, the more you will learn
Starting out you'll only be gathering twigs and grass, maybe chop a tree. You'll also gather basic food such as mushrooms and carrots. Then you'll start building your encampment, learning how the day/night cycle and the seasons work. Later on you'll start building massive farms, refridgerators, fortifications, and many other things. All of this is done for the sake of not starving.
As the game progresses, you will encounter mechanics such as drought, forest fires, the rainy, season, the cold and many others. To counteract these you need to plan properly and will probably die the first time around. Once your knowledge reaches a certain level, you'll be able to survive indefinitely.
Pro Unique mix of 2D and 3D art offers a change of pace
Don't Starve Together has a very unique art style that places two-dimensional characters in a three-dimensional setting. Even the waves in the sea look like cardboard cutouts used in a puppet show. This look and feel to the graphics is a nice change of pace from ultra-realistic games.
Con Steep learning curve
The first few attempts will last only a couple of in-game days. This is because the game has various punishing mechanics, which you can only learn through trial and error. One such mechanic is the darkness, which will kill you in under a minute if you don't have a light source. Followed by packs of hounds that randomly spawn to kill you. In most cases preparation is key and you can't prepare without knowledge.
Con Can get repetitive
You'll have to repeatedly collect a lot of basic materials like twigs, grass, and ore. This is because most of the starting recipes share the same required materials. Even later in the game you'll be doing many repetitive tasks. Gathering enough firewood for winter is especially bad because you have to chop down dozens of trees. All of this is made worse by the limited inventory space, causing you to make the same trip multiple times.
