The interview with Tyson Green (the lead investment designer for Destiny) is awesome. It addresses quite a few big questions I had on the leveling up system. The two best bits are that there are big desicions to be made when leveling that are permanent(or at least locked in place for a significant amount of time?). And that there are parts of the game designed to be investigated by the community and figured out in a way similar to dark souls.
I am assuming it will be put up on the website at some point. One thing i cant find is the interview with Jason Jones, looks like i will have to wait for it to be put up online despite paying the monies.
