jak3>jak2>ratchet:tod=ratchet2>ratchet1>daxter>ratchet3>jak1
i dont count either ratchet:deadlocked or jak x on the list. they might be good games, but they dont make the list.
considering the small margin of difference in quality past ratchet 1 (im currently playing daxter so i have yet to accurately rank it) the series slightly leans jak.
