There are some games where there is an in-game encyclopedia where you can know many things about characters and settings of the game. For example, the Codex in Mass Effect. I want to know if it is exclusive to Bioware, and get inspired about other encyclopedia systems.

What are some other examples of in-game encyclopedias? How effective is it? I also want some examples where the in-game encyclopedia is not effective at all or an ignored feature

The civilization series had an encyclopedie, that basically was also a definitoon for the rules of the game, but offering some additional hirostical information about the topic. I think it is well done... – tom van green Nov 12 '12 at 6:30
UFO: Enemy Unknown (1994) have in-game encycolpedia of some sort (Ufopedia). So it's definetly non-exclusive to BioWare. – Petr Abdulin Nov 12 '12 at 6:34
From the FAQ: What kind of questions should I not ask here?: "You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page." This is not a useful sort of question to ask here, and it's not a question about an apparent practical game development problem. It might belong on Gaming/Arqade. – doppelgreener Nov 12 '12 at 6:46
Not only Civilization, but also Colonization (Colonizopedia) and probably many other games by Sid Meier had an encyclopedia. Also, sometimes, e.g. in Mass Effects, encyclopedia is pure boring. I would love for ME and Dragon Age Origins to have 10 times less codex entries, but also 10 times more interesting. – Markus von Broady Nov 12 '12 at 7:59
Many games have something like an encyclopedia. Usually it is just a bestiary guide and a short blerb on the background on each character. My personal favorite is the one in Star Wars Rebellion, because they basically use it as an excuse not to give you a real tutorial (although there is a tutorial written in the game booklet). While the game is fun, the encyclopedia is near useless and just provides some additional facts that don't help you at all (or that you would have just assumed naturally). Basically it's bad because it's huge, presented all at once, and provides crap information. – Benjamin Danger Johnson Nov 12 '12 at 17:11

Metroid Prime games uses mechanism called scanning. The player can scan objects and enemies in the game for more information, which is saved in a log book. The background story of the game is also scattered as scannable text in the game world. If the player scans enough in the game or even everything that is possible, a small additional ending video is shown when completing the game. See

Pikmin 2 has similiar log book called Piklopedia, but the content is filled automatically. See

In both of these games filling the missing entries to the encyclopedias is a challenge on it's own.
