I dont like microtrailers because 6 seconds is not nearly enough time to glean anything about how the game plays. It holds no more information than a screenshot. It's very much no substitute for an actual trailer.
That being said, the "show" is just the top games in back-to-back microtrailer format.
Those x-box live segments with Larry Herb was a show.
Nintendo Direct is a show.

I dont understand why it's even pitched as a "show".
It feels like something that would just be on the store page...just as a thing. I might let it go thorugh a few games before i scroll down but it's not something i'd watch the entirety of on purpose. Let alone go out my my way with an extra click to watch the "show"
