Yeah, I am not too sure why there are two parameters that seem to be showing the same item (despite some variation between the two.)
Since 'popularity' is only seen in this endpoint, it may be there for the website/directory.
@DallasNChains - The 'popularity' token isn’t listed in the dev docs either (https://dev.twitch.tv/docs/api/v3/games ) - is this something that light can be added to the docs? (Assuming its not already been added to the V5 docs we will see soon). It’s still present of V5 so I assume it is still being used in some fashion.
