There's a channel called Sky9 games that's doing a thing similar to this making a game that's very much like PB3.
And Eric already has over 1k subs so he can apply for monetization and start making money off these videos.
Also the new viewers would find PB3 really cool and donate to the patreon, and also tell their friends.
I would recommend making a video like the testing out the gameplay features one but maybe in better quality?
Anyway these are just my thoughts, do what you want Eric!

EDIT: Unprivating the gameplay features might be a better idea. Should be easy enough.
