Phew .... thought someone was going to call a Zelda game underrated for a minute.
I love Best of the Worst, and while I think they deserve 20 million subs, I think they also get a fair amount of recognition.
I think what's far more underrated is the admittedly low effort but almost equally awesome side channel ran by Rich and Jack, where they cover games: https://www.youtube.com/user/PreRecRLM
