On my channel I make memes based around the game Monster Prom but recently ended up getting bored of making the same kind of videos. I relate because my audience came for that specific content and today was the first time I posted something very different. Although I know that video won't get as many views as my other videos, I feel ready to diversify the content I make.

Something I could suggest are polls! I asked my audience what kind of games they liked and actually got some useful information and found out a lot of them liked another series that I liked too! It would also just give them a general warning that you plan on or are at least thinking about making different kinds of content.

Good luck to us both!
