numOne, I agree, but I definitely won't have time for something like that.
kalababa, As an option, it would definitely be very cool, but I don't see anyone who would take on such a grand project. This work already implies the active participation of the streamers themselves, and they already have enough work besides streaming. And flash drives will continue to be used for a long time; their use doesn't require a constant, stable, high-speed internet connection, which, for various reasons, people may still not have.
As for me, I would add the few games that I consider to be at least somewhat "instructive" or simply interesting (if there was a place to do so). Because games that, for example, end in a victory/defeat due to a blunder usually don't offer much value.
