https://api.twitch.tv/api/users/<channel>/follows/games/live was an unsupported endpoint that has been removed.
https://api.twitch.tv/kraken/games/top however is available in v5 (although deprecated) and should not be returning a 410. I was able to replicate this one and have forwarded the behavior to the team to investigate. The initial response was that there was an internal server error and they are looking into why the 410 was sent instead of a more appropriate error code and message.
