How do I request to have the video explanation on a game's page changed?

[GHOST04]

This is the video explanation for 7 Wonders Architects currently https://youtu.be/-usPuWZyZwI

It is no bueno IMO.

I found a much better one https://youtu.be/SJvGd1MCMNE

How is the video explanation determined in the first place? and what is the process for having it changed to a better one?

you can thumb down the one you don't like, and add/upvote the other you like more (and ask friends to do the same if it needs more votes)
