Words from Urk! (Destiny)
He spoke to IGN about the beta
"The Destiny beta, in many ways, is being treated like a full product launch. We can't just carve out three competitive multiplayer maps this time around...We'd only be gathering data on one facet of the overall experience -- one that is arguably the least resource intensive and most well understood by our team. Destiny demands more...Our ambition is to build big, rich destinations that players can visit over and over again, to fill them up with great story and moments that they can share with their friends, and to deliver face melting action that leads to treasure, challenge, and discovery...We want to pour all of that secret sauce into the Destiny beta. It's a massive undertaking, but one that we believe will pay huge dividends for us, and for our players."
