If Diddy and Sims creator Will Wright were somehow combined, the result would be Eskil Steenberg.
Diddy is legendary for working hard, promoting his labors and making connections. He's the best. Wright talks about technology with a command and foresight that suggest he's already seen the future and is just biding his time in our humble era.
Steenberg, a programmer from Sweden who is making a computer game called Love, combines all of those traits. He's 31, so maybe he's old to some people, but the sense one gets talking to Steenberg is that his future is still open and that this guy is going to be huge.
