At the time, both YouTuber Dungeon Coach's DC20 and 13th Age 2nd edition were being crowd-funded at the same time. I ended up cancelling my pledge for 13th Age and moved it to DC20 because of the exposure of the DC system. It seemed that several times a day, DC was interviewing, discussing game design. It really gave the impression that he was trying harder, promoting more, and knew more about game design (which couldn't be true because 13A was created by industry veterans).
Unsurprisingly, 13A was actually released. DC20 is still in Beta with a designer who's relying on outsourcing the design to random playtesters.
I learned to not trust random YouTubers with game design.
