Nintendo seems to be the outlier in the video games industry in that they are very much willing to foster talent over a long term. People who started doing sprite work 35 years ago are still there today and directing games. It's almost like the secret to long-term success is developing a roster of highly-skilled professionals, rather than treating your staff as disposable.
Didn't know, that's pretty cool!
I do think Nintendo generally has a good sense of what they want from their games, so perhaps future generations will stay true to the current 'generation' of game leads.
