Ubi doesn't need somebody else to pay for development costs. That's where it falls apart. They're doing fine as a company aside from the hostile takeover. Capcom is the kind of company that needs development costs paid for for games
If a company comes to you and say look make us this game as a exclusive and we'll pay off everything and you get a percentage of the profits. Which CEO is gonna turn that down? Every company wants minimum costs and maximum profits.
