Complexity of Passwords
The complexity of passwords depends mostly on the number of variables stored. In games that only require the stage variable to be stored, a single word, with or without meaning, is sufficient. More complex games often base their passwords on several characters combined by an algorithm. While it is possible to translate saves into passwords even from the most complex titles, the practical use of them is very questionable. In games such as role-playing video games, where dozens of stats have to be stored, passwords would be hundreds of characters long.
In other languages with more characters, passwords can be shorter. For example, Japanese has many characters:
- numerals ... 10
- hiragana and katakana ... 46 to 83 each
- 46 normal characters (or 48 with rarely used ゐ and ゑ
- 9 or 10 small characters ... "ぁぃぅぇぉっゃゅょ" and the rarely used "ゎ"
- 25 voiced characters ... such as "が" and "ぱ"
- alphabet ... 26 (or 52 with lower case)
Japanese passwords can have more variables. For example, Japanese versions of Dragon Quest prior to the American NES version used passwords with many variables, while the North American version used a battery backup.
Usually, the size and complexity of the password does not make "guessing" a valid password practical. However, particularly in the case of algorithmic passwords, a password can be found by pure chance (such as the famous JUSTIN BAILEY code from Metroid).

Famous quotes containing the words complexity of and/or complexity:
“The price we pay for the complexity of life is too high. When you think of all the effort you have to put in—telephonic, technological and relational—to alter even the slightest bit of behaviour in this strange world we call social life, you are left pining for the straightforwardness of primitive peoples and their physical work.”
—Jean Baudrillard (b. 1929)
“In times like ours, where the growing complexity of life leaves us barely the time to read the newspapers, where the map of Europe has endured profound rearrangements and is perhaps on the brink of enduring yet others, where so many threatening and new problems appear everywhere, you will admit it may be demanded of a writer that he be more than a fine wit who makes us forget in idle and byzantine discussions on the merits of pure form ...”
—Marcel Proust (1871–1922)
