Technology is a central pillar of any interstellar empire. It has allowed them to reach the stars and it will be what allows them to succeed against other empires.

There are roughly 300 technologies in the game, though these will not all be available to the player in a given play-through. Engineering, Physics and Society technologies are researched separately using different research resources. There is no "tech tree", instead players are presented with a number of different choices of techs to research.

The card system

The "card" system.

Stellaris doesn't have a tech tree in the normal sense of the word, instead it presents the player with a quasi-random selection of technologies that may or may not appear later on during a playthrough.[1]

A good analogy for this process is a deck of cards in which each card represents a different technology. As soon as a tech is selected for research, the remaining "cards" are placed back into the deck which is then reshuffled. However, in this "shuffling" some cards are weighted to appear more often than others. This is especially common in the early game where some "cards" are extremely likely to appear as to allow all players to get a fair start. Additionally, an empires' ethos, the leading scientists' traits, the current researched technologies, etc. all factor in into this weighting.

Special technologies

Certain technologies are considered "special" and are marked in a different color so players can to recognize their rarity. These are techs that might only appear once in a playthrough and, as such, should probably always be picked.

There are also unique technologies that can only be learned via the investigation of anomalies, debris, etc.

After some time it's possible to reach a point where procedurally generated techs get a chance of appearing more and more often after many of the "normal" technologies are successfully researched.

There's also the possibility of having "advanced" techs appearing during the later stages of a game. These are high reward/high risk opportunities that can give an empire a significant advantage in the race to victory but may trigger terrible consequences such as crises. Some advanced techs are dependent on the species' ethos.

Technology types

Technology is divided into three types: Physics, Society and Engineering.

As a game progresses, the technology choices for each empire will begin to include progressively more advanced and correspondingly more expensive technologies, meaning that building research labs and stations should be a priority. Technology costs also scale with the size of an empire's population,[2] which makes it possible for small empires to maintain technological parity with larger ones.

Categories

Each technology is also part of a category, which are independent of the three types. So far the following categories are known (category names in italics are speculative):
