Scarfulhu is a more soothing gaming YouTuber. He is almost exclusively a reviewer, so he isn't a Jack-of-all trades sort of channel (like many others). But for the most part, he enjoys dissecting point-and-click adventure games, a niche that's continually growing in popularity.
His frequent discussions regarding puzzles, pacing, and overlooked gems from the LucasArts and Sierra eras (as well as the modern day) make for very relaxing videos. On top of that, Scarfulhu does occasionally have live actions skecthes, but they're much calmer and drier than your typical frantic and hyperactive YouTube personality, which is a nice change of pace.
This all compounded by his -- once again -- dry sense of humor, as well as his delightful Northern English voice and accent. That and the scarf, can't forget the scarf.
Scarfulhu also occasionally reviews movies, usually outstandingly poor animated films and mockbusters such as Ratatoing and Elf Bowling: The Movie. On one occasion, he even wrote a comedy skit that ended up being performed by the famous YouTuber TomSka.
Scarfulhu is just a pleasant guy with an equally pleasant channel to watch. On top of that, his is also a very clean channel, with very little language or violence. So if that's a draw for you, then there's that too.
