Huh.. I haven't even heard of most of these. With all the time I spend on Youtube that's a surprise.. Anyway:
1. Cinnemassacre
2. ALT SHIFT X (In depth Game of Thrones stuff mainly)
3. Red Letter Media
4. Channel Awesome/Nostalgia Critic (but mainly the older stuff)
5. GameXplain (Great mostly Nintendo-based channel)
Couple of honorable mentions:
- Nightmind (sort of like creepypasta with vids, talks about horror movies/vids as well as some more just surreal/trippy stuff)
- The Rubin Report (basically shares my politics, very intelligent and sensible host, has various guests on with interesting disscusions, calls himself "Classical Liberal" ie. anti SJW/authoritarian type liberal.
- Used to LOVE Epic Meal Time but they completely went to shit 3 or 4 years ago.
