This is just like the
Special Stars thread, except this one's for discussing changes between Vault and Moon tiers. If you see a Vault run that you think deserves to be upgraded to Moon, or vice versa, then post about it here. If you suggest a Moon movie be downgraded to Vault, then it has to qualify for Vault: No playarounds, no arbitrary categories, no sports games, to name a few guidelines.
For reference, here's all the Vaulted movies on the site, organized from highest to lowest rated:

I'll start with, what else,
Hydlide. This was a huge topic of debate around the time it was published, with a lot of people (myself included) thinking it was entertaining enough for Moons. It makes an unplayable game look entertaining and fast, and with AVGN exposure from way back in the day, I think it needs a bit more of a presence on the site without having to languish in the Vault. The rating's still quite good, too, and there are plenty of Moons that are less entertaining than it.
EDIT: Also, should we elect someone to handle these tier changes? A Moonkid to go along with the Starman, perhaps?
