Wasn’t No Shave November the movement that was supposed to bring cancer awareness?

I think OP is talking about the kind of lore deep dive videos, not necessarily the normal gameplay “Let’s Play” style videos.

Saving this comment so I can check back after I get Secret Project 3.

There is a similar game that recently came out called Humanity. It’s missing a lot of the charm of the old Lemmings, but it’s spiritually in the right place.
