YouTube wants you to have a trailer for your channel maybe 30-60 seconds long but I did my own thing by compiling the greatest hits of clips from about a year's worth of material.
So, on my channel we film arcades, expos and play 8-bit console/computer home brews, old brews, prototypes, works in progress and hacks. I usually play games with my kids and we will grade the game.
I play a father that thinks modern games are crap and spends all his money on video games instead of providing basic needs for the children like food and clothing. I'm also delusional in thinking I'm a "YouTube sensation" after hitting 100 subs.
