Let's Plays are a series of videos covering a video game.
The point of this channel is for Let's Plays (AKA LP's). Johnny created his second channel so him and Elliot could do LP's and not put them on their main channel. Since then, many people have been featured in Johnny and Elliot's LP's.
BrainScratch Commentaries does commentaries over video games which are very similar to LP's. In 2013 the 4 main members of BSC went to Momocon 2013 and they recorded some LP's of games like Mario Party 2 and Kirby's Return to Dream Land with Chuggaaconroy, one of the most popular LP channels on YouTube.
