Just for those who missed it, I do recommend having a watch of this BBC documentary:

The Supergamers.

I'm not sure if this is the right forum for such a link, but I thought it was a pretty interesting look at something that's not especially mainstream, but has the appeal and cogs in place to make a mainstream breakthrough in 2016. It's about an hour in length.

[NB: I apologise to those who, for regional reasons, can't watch this. I'm in Blighty so... I'm not sure who can and can't watch this. >.<]
