Ken Kutaragi: The man not only helped Nintendo but also got Sony into the video game industry, and fuck, for any engineer or technophile, this guy is a god.
I also liked Harrison and Hirai only while they were working under Kutaragi, I wish Ohga would have stayed longer, fuck Idei.
As for others
Kojima: What? He is considered an exec!
Carmack/Sweeney: What is there not to like about them? They know their shit, no one fucks with them
Ted Price: He just seems like a cool dude :lol
As far as Nintendo goes, the only one that I think I would have like would be Gunpei, truly Nintendo's best, imo that is.
