SPELLING RULES
In game text, numbers can appear in different contexts: as mission descriptions, rankings, date, time etc.
For game mechanics, as skill descriptions, missions, and other values, use numerals even if the number is smaller than 10. It is shorter, and some strings may have a similar sentence with a placeholder code, like {n} or %s, that will be substituted by a numeral later. Try your best to avoid using plural marks, as in "coisa(s)".
One solution is to rewrite the sentence as below:
Incorrect: Concluiu %s missão(ões)
Correct: Missões concluídas: %s
For other content, like announcements, story, and dialogue write the all numbers smaller than 10, and use numerals for 10 and above.
Please make sure you are using periods as thousands separators, and commas as decimal markers.
ABBREVIATING LARGE VALUES
Some games and social media functions will require large numbers to be shortened. Please use the formats below.
1.23 Billion = 1,23 Bi
1.23 Million = 1,23 M
1.23 Thousand = 1.230
For thousands, the shorter way to write is the numeral form. Avoid the foreignism k. If source is a code, like {n}k or {n}千, add a space and write mil after it.
Incorrect: Obtenha {n}k Moedas de Ouro
Correct: Obtenha {n} mil Moedas de Ouro
