This might seem like a tedious, time consuming "achievement", but don't worry, if you've never been on YouTube for gaming videos (like me, prior to my ex), you have no idea what to watch.
Here are some HILARIOUS suggestions, just watch a few episodes from these channels, you'll probably end up falling in love them.
Markiplier (Scary Games) - Lots of hilarious jumpscares, I quickly fell in love with this guy.
Markiplier (Five Nights) - Just watch them.
Dashie (Scary Facecam Games) - He's obscene and loud.
GameGrumps - Dark Souls III - Just watch them, I love these guys (Arin = EgoRaptor for you old NewGrounds people).
GameGrumps - Sonic Adventure DX - I literally cried from laughter in some of these videos.
GameGrumps - The Legend of Zelda: The Wand of Gamelon - Helped me with a break-up, stupid funny.
There's well over 5 hours, and I've watched these playlists a few times over. If you don't enjoy at least one video, go to the hospital or call a doctor, because you are dead.
