It seems to me like a good idea, but a few things really need work.
The two biggest bugbears are the game selections and time allotted to each game. More time needs to be given to fewer games, every time I started to get interested in one it moved on to the next thing.
As for the game selections, they're largely a mixed bag. I already know about PUBG and CSGO, ok valve? You don't have to tell me again. The most interesting parts were the random games out of left field and yet the emphasis seems to be on the games that are already popular. A quick lead with the top sellers is fine but when I saw that half the "firehose" was a repeat of the top sellers I quite watching. Sometime of guard against this kind of redundancy is essential. And how about some old games? It's not like there's a statute of limitations on quality.

Technically, it was a real hassle to not be able to open separate instances to check out the games as they stream by, and I instead had to manually notate them for later. No problem I figured, I'll just open it in fullscreen, move the vid to another display and check out the games on my main window as they scroll by. In a web browser this would be no problem, but since I'm shackled to this bloatware client naturally it can't just work. Going to another page kills the vid playback and even the button right next to the vid that's supposed to instantly take you to the game you're viewing doesn't update when you're viewing in fullscreen. Beyond that, having two store link buttons, one for the current game and one for the last game shown would be very helpful for those moments when you're just too slow on the draw. Further, if we can't just open a separate, independent instance for the vid playback a la steam streaming, it would be nice if the client could at least cache vid progress.

All in all the best thing about this was the variety presentation in an easy digest format, and the fact that it doesn't appear to be search bubbled and "personalized" so I can actually expose myself to interesting things I don't normally see.

Oh and I think the Monster Hunter entry shows The Witcher instead.
