Zynga, which has made its fortune on Farmville, has released an app in Canada (not on the American App Store yet) called Dream Heights, which bears much more than a passing resemblance to Tiny Tower, a terrific and very successful freemium game from NimbleBit (the brothers-run company that we've posted about a few times before). By the looks of things, it seems that Zynga saw NimbleBit's success and decided to borrow most of the game's mechanics.
