Skill tree

Simplified representation of a skill tree using the example of weapon use

The skill tree (or: skill tree , talent tree ) is a visualization concept in computer games . It allows the simple graphic representation of a hierarchical progress system. A skill tree consists of several nodes that represent different abilities or extensions (sometimes also called "perks"). These nodes are interconnected and can gradually be unlocked for a character or an object.

construction

A skill tree consists of a tree diagram of interconnected elements. The focus is on the game character or the object for which the skill tree is being built. From this central object, categories branch off which represent the skills or properties.

Activation of an element is a prerequisite for activating other elements connected to this element. A skill tree can thus be described as a directed graph (see graph theory ). Branches can not only diverge, but also come together again, which means that a skill tree can also be structured in a circle. There are costs associated with activating elements. These can be play money, experience points or another unit. Activation unlocks certain advantages such as skills, upgrades or bonuses for the character or object. As a result, skills and game content can only gradually be made accessible to the player and the complexity of the game gradually increased.

In some games, elements can be deactivated again and the points used can be regained in order to redevelop the skill tree. (e.g. Skyrim ).

Significance for the course of the game

The development of skills often contributes significantly to the development of a character and allows the player to choose specializations. Especially in role-playing games, the player is therefore forced to choose branches that affect the further gameplay. Often the player has to make compromises and for example forego other skills. The skill tree therefore also makes it possible to promote different types of players in different ways. However, the player can also feel "badly skilled" if the skills he has acquired make the game too easy or if he is too fixed and it is difficult to unlock new skills. If a player deals in depth with the planning and optimization of the skill stress or character patterns, theory crafting (in German about as much as theoretical craft ) is also spoken of.

commitment

The following list shows some popular computer games that use skill trees to develop characters:

Ancestors: The Humankind Odyssey

The game Diablo II from 2000 is described as the first game with a greater depth on the skill tree.
