I am an experienced game developer. I estimate I have 14 years of programming experience, and look how many games I've released. I will be working in game development from 2 August, less than two months after graduating from Cambridge University, and I have made some connections in the gaming industry.
Harbinger is an experienced game developer. I would estimate he has at least four years of experience (on and off), and look how many games he's released. As far as I know he is not working as a game developer, but he has made connections in the gaming industry. (Do you believe this last part?)
Now, this is very, very important. There is nothing wrong with being less experienced or less skilled than other people in a given field. I would never pick on someone for not being able to write games. But when someone tries to lie their way to the top of the ladder, stealing all the attention along the way, we bite.
I'm crap at Japanese. The Japanese Studies students at Cambridge are all way ahead of me. They're like wow. But no one picks on me, because I don't pretend to be better at it than they are.
