Even though I'm not a Minecraft junkie, I've got to say that's pretty genius marketing/promotion.
Did the idea come from the client or the developer?
Wonder how much real world work gets done on office computers versus
virtual construction.
Maybe they prototype all their development work on their own MC server?
Inquiring minds want to know.
Stop by and interview the relevant parties and sell the story to WIRED or various Gamer mags/sites/etc. More Promo for them, $/£/€/Bitcoin for you.
