Fish Tycoon (Nintendo DS, 2007)
The DS gets its own version of this popular casual PC game, complete with the requisite touch-screen controls that let gamers breed, feed, and heal fish with the flick of a finger. Gameplay remains the same from the PC version, with gamers attempting to grow a fish franchise by balancing breeding, tank decoration, sales, and marketing. The DS version of Fish Tycoon gets seven new brands of fish, yielding more than 750 potential species, and a new 3D view lets gamers see their fish better. Players make money by breeding the most exotic fish possible, with the "Seven Magic Fish" yielding the most cash.
