If he just wants to make money, he’d be better off churning out a Diablo clone or some generic RTS.
there is a difference between Schilling's objective and the one he has to pitch to investors.. as i said earlier, he is probly more interested in the competition angle. youd have to think like some kind of "baseball hero" or "sports champion" or so forth to really get it - its more about proving his own competitive worth in the face of massive odds.. a sort of "they think they are hot shit, but they havent met ME!" kind of attitude is usually the one that fuels competition to the most extreme intensity. he might think that WoW is soft for lack of competition, that they are ripe for a fall.
of course you dont understand the reasoning for why he is doing this and what angles he has to present to other people to get them on board. you are trying to approach this with your own perspectives and somehow transpose them onto what you feel would be the logical route to take in such an endeavor. it doesnt work like that - you have to step outside of your own subjectivity to understand the subjectivity of others
