Let me tell you, writing comics is as hard as anything I've ever done - for me, at least. I'm now officially in awe of guys who can crank out multiple books a month and maintain a high level of quality. Comics are completely different than any other medium I've dabbled in.
Third-person camera is way harder than I even imagined it could be. It is the hardest problem in video game development. Everybody gets it wrong. It's just a question of how close to right do you get it.
Creating a really believable world is just insanely hard
