At the Game Developers Conference in March, Bungie’s David Candland gave a really cool talk about the evolution of Destiny’s UI. Among other things, he showed a bunch of prototype menu screens, and also explained the complicated process of fine-tuning a video game interface.
GDC has posted a full video of Candland’s talk to YouTube. If you’re interested in this kind of stuff (or if you just play a lot of Destiny), it’s totally worth checking out.
My favorite part is the part early on when Candland talks about figuring out how sticky to make each UI element as the cursor passes over it.
