I dunno. Best guestimate I have. Handheld games I generally beat once or twice and go through a ton of reruns but never stay interested long enough to make it to the end. PH and ST are kinda of a different story, but I haven't had them for that long. The 3D ones I always play, so I've done countless playthroughs all the way. WW's probably the one I completed the least amount of times out of the four, followed by MM, then TP, then OoT.
