'''Technology''' is a central pillar
in any interstellar [[empire]]. It was with it that allowed them to reach the starts and it 'll be by it that can make them succeed against other empires.
== The card system ==
[[File:Card system.png|right|thumb|The "card" system.]]
[[Stellaris]] doesn't have a tech tree in the normal sense of the word, instead it presents
to the player a quasi-random selection of technologies that may or may not appear later on during a playthrough.<ref name="dev_diary_11">[[forum:893377|Dev Diary #11 - Research & Technology]]</ref>
The best analogy to this is by imagining a deck of cards where each card represents a different technology. As soon as a tech is selected for research, the remaining "cards" are placed back into the deck and reshuffled with other ones. This "shuffling" is not completely fair, however, since some cards are weighted to appear more often than others. This especially happens in the early -game where some "cards" are extremely likely to appear as to allow all players to get a fair start. Besides that, an empires' [[ethos]], the leading [[scientist]]s' [[traits]], the current researched technologies, etc. all factor in into this weighting.
== Special technologies ==
Certain technologies are considered "special"
in the sense that these are marked in such a style as to recognize their rarity. These are techs that might only appear once in a playthrough and, as such, should probably be picked.
There are also unique technologies that can only be learned via the [[survey|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
that much needed edge to [[victory conditions| win]] but may trigger terrible consequences such as [[crisis]].
== Technology types ==
Technology is divided into three types
, which are: physics, society and engineering.
