You could also base it on a popular game, like what he did for R64: Freddy's spaghettiria and SMG4: If Mario was in. You could actually spend time coming up with a completely original idea, or you could just make a meme out of a preexisting thing.
But what's actually important is coming up with a good idea. Luke says that if you're a YouTuber on the rise, you're probably overconfident and think you're ready to meme it up on the internet. He says that there are many parts to making SMG4 videos like he does.
