Since my last post in this thread was about 2 years ago, an update on my viewing...
Watch less YT now than I did, probably been low for about 5 or 6 months now. Haven't watched as much TotalBiscuit or Nerdcubed as I used to, but occasionally tune in. Still catch all Angry Joe's reviews, which are still great.
I like analysis more than dry reviews or let's-plays, and my preferred YT-ers tend to reflect that.
A few newer additions to my watchlist:
Jim Sterling - probably watch more of his stuff than anyone else at the moment. His Jimquisition video on a Monday is always worth a look, and his other videos are enjoyable and nicely bitesize.
SuperBunnyHop - don't always watch his reviews, though they're quite good, but try to watch his other content (analysis or history of some aspect of a game/gaming). Usually very interesting and well put together.
Stan Burdman - he's returned to YT after a long time out. Really enjoy his style, makes me laugh especially when he plays awful games.
