But I actually did fairly well. I know excellent devs that were making <$50k/year leading teams delivering hundreds of millions in revenue annually, and they maybe got another 10 days of vacation.
However, let's say that you come up with a game idea, design the game all they way until it ships and then it does gangbusters well, making the company millions and millions. Getting some serious appreciation doesn't seem far fetched in that case, like CliffyB and such got, to give an example. But if not that, at least some generous bonuses and promotions would be expected in an Euro-American company.
Apparently not for these 2 guys. That's what I was referring to.
In the games industry, that would probably only happen in you developed the entire game yourself and only needed a publisher. If you need to take payment in advance for development, you would also most likely lose the IP.
Both Takahashi and Iwatani were Namco employees, so they wouldn't get to keep any IP they developed within the company. But that doesn't stop the said company from giving them bonuses and promotions. Doesn't seem to have happened in their case.
