Some tags have the game: prefix. I don’t think it’s an official site tag prefix. It looks like it’s only used for fan projects, not official games.
Some fan games don’t use the game: prefix, like minty fresh adventure or story of the blanks. Some have both? eg. game:ambient.white/ambient.white, game:filly astray/filly astray
Is there any convention to apply, here?

As far as I know, tag prefix aren’t supposed to have a space following the colon, but some of the game: ones do including a couple that are already categorized and have tag descriptions, so they’d need a mod to fix them.
