i wanna try and get into YouTube. [I Like Youtube]

I wanna try and get onto the gaming platform of YouTube like Lets Plays and all that. But is it hard? I'm someone who loves a challenge but sometimes a challenge can be hard as titanium.

Occasionally I think its just have a laptop with games and editing software on it, get a mic and start playing but other youtubers make it look so hard.

I for one, won't be doing this for cash, just as a hobby.
