What are the most popular games right now (BESIDES COD Ghosts and Battlefield 4)?

I just started a YouTube gaming channel called Dr. Phantom (http://www.youtube.com/user/DrPhantom99)

I just have a Minecraft Let's Play, tutorials and the Minecraft for PS3 news.

I'll make a Left 4 Dead 2 Let's Play and modshowcases.

I'll buy COD Ghosts and make videos of it.

What other games are popular that people watch a lot in YouTube and what do they watch of them? (Let's Play, Multiplayer, Tutorials, mods)?

The walking dead season 2 episode 1 is really popular at the moment. Its also very good fo youtube.
