I like lets plays because I like seeing how others play games and the conversations they have. It was a new form of entertainment for me. I love video games and growing up I enjoyed watching others play games, I liked seeing others strategies and how they react in certain situations of the games.
I love the Game Grumps cause they are a group of guys bullshitting on a couch while playing games, it's the same thing my friends and I do when we hang out. I couldn't get into Pewdiepie mainly cause I'm not into the whole scream at the screen while someone plays a game.
The youtubers I do choose to watch seem like they have a lot of fun and it inspired me to start my own channel and I don't expect to get to the levels of the grumps, markipliers, jacksepticeyes, etc but I am having a blast doing it, I love entertaining people, and plan to continue doing it for awhile :)
Sorry for the long winded response.
Best regards everyone
