Source hierarchy
We prefer the developer's own words, then the storefront record, then official media. Community posts, videos and other wikis are useful for finding questions, but they are not used as the basis for a factual claim unless the claim is clearly attributed to them.
- Mossbomb's official site, press kit and store copy. The primary source for dates, prices, features and scope.
- Steam store pages and API. Used to cross-check release display, languages, features, system requirements and screenshots.
- Official screenshots and trailers. Used for visual observations that are not spelled out in text. We label them as “official media” and do not infer hidden numbers.
- Community sources. Not used as primary evidence. If we ever cite one, it is labeled and kept separate from confirmed facts.

If a source is wrong, a timestamp is missing or a page overstates what is known, send the correction with the source URL and the exact claim. We will update the page and the review date rather than quietly changing the text.
