I would kind of take advantage of the fact that my dream job is HIS job so yeah I'd take the chance, only if he's 120% sure that he wishes to leave the job. I'd probably try to act as much like Adam as possible, then start merging over to my personality so that people can give me a chance. I wouldn't make a HUGE change, but eventually when I settle in I might.
Then, I would probably try my best not to flirt with some of the team... just because some of them are majorly cute, in my opinion. Then I would play some minecraft with my sister to make her become more popular so that she can be popular with me, then she can pass on the popularity to her boyfriend's channel. I hope that would work out though, because I'd be expecting that most of the fans would unsubscribe. Not only would I help my sister, but I'd help my best friend too. She won't admit it, but she wants the same job as me. She's afraid that I'll get mad at her because I usually get mad at the fact that she copies most of what I do.
I was completely honest here, so I hope that no one yells at me for taking advantage of the fact that I took over ownership of a channel that's in the top 200 most subscribed of YouTube. Hey, it's my dream to be a minecraft YouTuber.
