Favorite YT Channels
Not ordered (but FSG is #1 and Dead Meat #2)
Channels devoted purely to hosting speedruns are not listed, channels like Karl Jobst would be fair game, but even someone like Ender (who's Nidoking and PokeDoll videos were fantastic) will also be out of contention, just due to sample size. I want to keep this relatively unbiased. Channels devoted purely to making music are also out.
