Let's Player Reviews
The secondary series on Arm4g3d0nx's channel was a Let's Player Review series, where he reviews one let's play of certain let's players and gives them a precentage score; if he gives them an 80% or higher then he'll subscribe to them. For the first two videos he only reviewed one channel per video, but for the next 4 he reviewed ten per video.
