Topic to cover

Looking for topics to cover in my youtube videos for when im not doing live coms. I'd really appreciate it if you guys could share any ideas.

Well, what games are you going to commentate?
You can talk about little tips that can help a lot, for example, in many FPS games, aim down sight right before turning around a corner, because then you're already prepared for a gun fight and you already have an advantage over your enemy. Little tips like the one I just mentioned are nice.

You can also talk about things that happened you in game, like a bug where some dude was flying, etc.

Talk about your own funny stories, life experiences even, give tips and just try and engage with the audience, commentate on their level.
