The subtitle of the steam page is let us entertain you. And if it's meant to inform you the long-ass
boring video and lack of anything that couldn't be delivered in a written list kind of make me think they have the wrong idea of what informative is.
If they get the voice over to work it might actually add something that makes it worth occasionally watching, but without it I don't see the point.

Well that's a valid point you got there.
Still I was just watching those short videos of the games and if it looked promising to me I would take a closer look at the game. The important part for me there was to see gameplay and not to read about it - that's why i like this format more than a pure written one.

I didn't read that a voice-over was planned, but if that's the case that would really improve this thing.

Anyway even if it would stay as is, I'd watch it if I was looking for new games. Reminds me of the advertisment VHS for games that i used to watch as kid.
