Well, chewing it would be the toddler's approach to examine new things. IIRC. the amount of nicotine released when you chew it can easily be life threatening for a small kid. Anyway. I get what you meant now, so, yeah, metaphor delivered (with some help)
I can't really believe they are thinking to deliver a quality gameplay experience from a
competitive perspective, but they certainly deliver a quality gameplay experience from the
fun aspect of it (which has always been predominantly important to me myself).
However, I'm uncertain as to how good the shoutcaster would be for shoutcasting competitive matches, as for doing that you'd need some deeper insight into the game's tactics and mechanics. But of course that could be acquired, too. Overall the shoutcaster transports a lot of energy and manages to keep up the interest, entertaining to listen to.
Maybe someone should post a link to this discussion in the video's youtube commentaries - "commentary review" ;o)
