Yanen I think the writer has got to the point where he is extremely frustrated by the amount of "idea-guys" that take game development lightly, and I can relate to that.
I've got a number of requests like this since I started offering a freelance art service. One particular example was a guy who went to the trouble of GUESSING my Skype handle and adding me there so he could talk to me. He was extremely young, had no coding skills, no means to pay me, and I was the only person other than him that would be on the team.
Of course I said no.
Contrast this with the latest request I got, and that I have accepted; The guy emailed me extremely professionally, laid out his game proposal and provided a working prototype that had all of the core mechanics included, all coded by him. I took the work because he had something tangible to show me, and that was a guarantee to me that he was invested in the game concept.
