I would love to sleep on a bed made of your voice.
But really, you should always have a short intro. Like. Less than 5 seconds. I always liked the
Rocketjump and
Corridor Digital intros.
If you're not a personality guy, then act like a personality guy. I know that most everybody says 'be yourself' but I completely disagree. If you're some chump cunt that can't make commentary for stuff, then you should fake it. Act like a guy that can make commentary.
Also, try not to make insanely long episodes. Make things to the point. People don't want to sit through an hour of you saying things for maybe 5 minutes throughout the episode, but gameplay and no commentary the rest. If I wanted to see what warframe is like, I'll go watch a walk through or something. Cut things out that aren't interesting, and if / when you get a large enough base, you can upload raw footage of things to a second channel(The super fans will most likely love raw footage).
your channel's icon graphic is sick
This. If you've got like an extra 10 bucks to spend, you can pay Filipe1020 to make you an intro and most likely a channel logo(the actual price for an intro according to him is $3, but $10 would sure as hell get you a good channel icon and a good intro). It's very much worth it if you ask me.
