When are people going to understand, as Yoshida himself has even said, that money isn't everything? You can throw as much money as you want at something, it won't make it go faster, won't make it perfect, and won't make it necessarily successful. There are thousands of examples of companies throwing money at a project and it still going belly up.

It's a question of reasonable use of manpower. Every new race, as Yoshida said, is thousands of hours of work hours needed that could be spent more effectively elsewhere (since ultimately, races are nothing more than cosmetics, not game content).
