It a money thing. More advertisement, better score. But Zelda is a rare gems that i can said hasn't started getting bad. Yes, it always the same story with different character, there no timeline, a new gimmick each time, the same boss, etc. But it not holding them back. I have the same fun with OOT that i have with TP and even WW (even if nintendo has make a point to make sure we are not same on a large bound of water. YES i was 6 years old when i played SMB3 and that fucking giant fish leave a permanent mark in my psyche. Bite me!)
