This is about a problem in LibreGameWiki and (presumably) DatabaseQuery.
Look at https://libregamewiki.org/List_of_games#T.
There are 3 fake games at the letter T that the list of includes, all pulled from Template pages: Template:Gameinfo and Template:New-game.
The entry names are "Example Game", "[[Template:Gameinfo|]]" and "[[Template:New-game|]]".
I believe this is because DatabaseQuery does not correctly filter out content from Template pages. These template pages themselves include a Gameinfo template (or an example thereof).
So I think the solution is to make sure that only articles in the main namespace (and not Template:) are pulled.
