So, to get straight to the point: I am not entirely sure what content I want to create on my channel. Obviously, it should be something I love doing, not going for trends or views (and my latest video was a lot of fun to make, honestly). I don't want to be a meme channel, though, or at least I don't feel confident in doing so full-time (as a future outline, this was merely something I felt like doing.

Since I need to grow a specific audience that would watch my content I was wondering what I could create that I would enjoy making and possibly add some uniqueness to the scene.
I love to play a bunch of different games and genres, I rarely ever focus on just one, and most of the time I am not really up-to-date with gaming news and don't enjoy speaking like a waterfall either unless I was invested (thus a gaming news channels and dedicated one-game-content channels are out of the question).
I don't want to be one of those cringe youtube channels that screams or has massively flashy videos to keep people's attention, that is just not me.

I came up with one idea just now that may possibly be unique in its own way and still allows me to do what I love (and do anyway to a degree). For now, the idea is that I play any game I want and record it (voice and facecam, although facecam would not constantly block the screen) but do so in an entire sitting. Let's say I play through subnautica entirely or any game (no matter which game) and it goes for 20 hours straight. I would play it for 20 hours and only stop once I have completed it. When editing the video I would massively compress it, obviously, only showing the highlights or important parts.
I don't speedrun games and tend to take my time with things, thus it would likely reach over 8 hours in raw footage, no matter which game.

What do you guys think or are there any other ideas or suggestions? I would love to read them!
