Slime Rancher

The game is played in an open world and from a first-person perspective. The player controls a character named Beatrix LeBeau, a rancher who moves to a planet far from Earth called the Far Far Range to live the life of a "slime rancher", which consists of constructing her ranch and exploring the world of the Far Far Range in order to collect, raise, feed, and breed slimes. Slimes are gelatinous living organisms of various sizes and characteristics. To progress she has notes left by the former owner of the ranch that help her on her journey through the Far Far Range.[4][5][6][7]

The game's main economic aspect revolves around feeding slimes the appropriate food items so that they produce "plorts", which can then be sold in exchange for Newbucks, which are used to purchase upgrades to the rancher's equipment or farm buildings. Except for the basic pink slime, slimes will only eat one of the three types of food; fruit, veggie, and meat. Slimes have a favourite food, if they eat this food they will produce double the normal number of plorts. The player moves the character around a variety of environments and can collect slimes, food items, and plorts by sucking them up with their vacuum tool (called a "Vacpack", a portmanteau of vacuum and backpack). They can only store a limited number of items and item types at a time and must go back to their ranch to unload their collected items before being able to collect more. The player must buy and upgrade various enclosures to house their collected slimes and farms for storing their food. Upgrades can also be aesthetic upgrades to the character's home, Vacpack, and the ranch itself.

Different types of slimes can be combined and enlarged by feeding a slime a plort from another species, making them noticeably larger and able to produce two plorts (known as "Largo" in game).[8][9][10] However, if a slime combines more than three traits by eating a third plort different from either species of slime it is combined with, it becomes an aggressive malevolent black slime called the "Tarr", which devours all other slimes around it as well as being able to damage the player. The player can pump fresh water from ponds and springs to splash and disintegrate the Tarrs.

There are different kinds of slimes in the game, which all differ from small traits like simple ears, wings, and tails, to the ability to teleport or grab a chicken via a vine that emerges from the ground. Some of the types of slimes available in game include, docile (not feral), harmful, non-farmable, and feral. Most slimes also have a Gordo version of themselves. These Gordos are extremely large and cannot move around like regular or Largo slimes. These are found across the Far Far Range. Players can shoot food items at them until they explode, to gain normal versions of the Gordo slime's species. When exploded they also produce crates containing random loot as well as either a teleporter or "slime key" which allow access to new areas or fast-travel between known areas.
