The ideas are cool, but any situation where it's playing multiple videos at once is way too much stimulation. All iterations should have a one at a time function. Even if it just plays the first, ends the video, then plays the next. Scrolling should stop prior playback, or only play what's in focus. TBH though, for my personal preference the autoplay trailers on existing game pages, or the on-hover clips from existing lists are fine for me and these microtrailers don't add any value that doesn't already exist.
