It is true that is most of what you need. However in my experience (which isn't games but software development for some pretty expensive and complex equipment) successful projects often have a handful of talented people who give a damn well beyond a simple desire to earn a paycheck..

Big companies do a pretty good job crushing those guys as it is, yet somehow they keep springing up like weeds. If they ever actually succeed in killing the goose that lays the golden eggs...then you just have software like they have in India. How many cool games do you see come out of India?
