I remember when I was a little kid and basically posted on dev fourms as an "idea man".
Now I have a very good knowledge of C++ and a good deal of other programming languages (lua, c# (torquescript mostly), basic, php), have created many programs, can model somewhat, have played and understood many differnet genres of games, and have read about/seen many game projects fail and succeed. And I'm still worried about sounding like an "idea man" type of person.
