It's a conscious decision, because I'm a Zelda player and there are many official titles I've tried, in the creative moments of my game always have in mind certain sounds that I've ever heard in the saga.
Throughout the game, you'll find sounds from Alttp, LA, OoT, MM, WW, MC, TP and BoW. Each one has a particular use as I try not to leave anything random =p
PS: I realized that the word "concho" doesn't exist hahaha, it's just an expression from my country of origin (Chile). I always try to speak as neutrally as possible, but our country is known for having a very particular Spanish.
