I maintain the "Reliable Sources for Video Games" and "Situational Sources for Video Games" Google Custom Search Engines (GCSEs) for WP:VG/S. My methodology is simple: if it's an RS according to WP:VG/S's List or Checklist then it gets added to "Reliable Sources for Video Games". If it's situationally reliable, it gets added to "Situational Sources for Video Games". If it's neither then it doesn't get added. In other words, I will not add sources to these GCSEs unless they have gone through the discussion process at WP:VG/S and achieved broad consensus. Localized consensus for the reliability of a source is good evidence that a source is reliable, but it must be presented at WP:VG/S and a case built for its RS-determination before I add it to the GCSE. If there are any errors in these search engines, please contact me on my talk page to let me know so that I can attempt to correct the errors.
