The two most important things are:

1. Make sure you actually know what you're doing. Play a game you know a lot about.
2. Make your videos about the game you're playing, not about you.

I kinda had an idea already, i just wanted to make sure i knew. I might try this, but i need a capture device first.

Another question though, do LPers necessarily need to know where all the secrets in a particular game are/show them?

Not necessarily, but it's nice if you do, just to be thorough.

and sometimes it keeps commenters from being huge massive A-holes

Watch the Retsupurae series. Pay attention to what the Let's Players are doing, so that you can do the exact opposite.

Number 2 is so important. You have no idea how much I hate hearing things like this "I threw my controller like 50 times and broke it on this part its so f*** frustrating." Or "Man I drank like 50 Moutain Dew's and ate all this pizza."
Also speak clearly and try to keep profanity to a minimum.

Less of a question, more of a muse I guess, but does anyone else suffer from motion sickness when playing anything from a first person viewpoint?
The constant shaking of the camera, its sensitivity to most movements... I know FPSs are more natural for some people, but they're straight uncanny valley to me.
Does anyone else have this problem?

yeah, probably

anyone read about nintendo not doing a E3 press conference this year any thoughts

Edit: for those that did not know iwata is now nintendo of america's CEO

They're still going to show off all of their stuff so i mean, it's not a big deal. there just won't be one huge presentation.

Maybe they're saving their big guns for that Tokyo show, i dont recall the exact name right now. Its later in the year after E3 right?

the Tokyo Game Show

and no, not really

they don't need these events to announce things anymore when they can just do that with Nintendo Direct

but who's body will be ready at this years E3

Then they will most likely save everything for those then, so they can just announce stuff when they're ready, gives them as much time as they need.

You're missing the point. It's not about saving stuff for a later event, they're announcing a s*** ton of stuff at E3, they're just not presenting them in the same format. It doesn't mean less stuff will get announced than any other E3, or anything like that. They're just going about it in a different way.
