I would love having an MQ for this game. It's definitely the hardest 3-D game in the series, and the only ones more difficult are AoL and the second-quest of LoZ.
I actually wouldn't mind, just as long as there wasn't a kick-in-the-face section like Spirit Temple MQ. I wouldn't enjoy any... weird puzzles either. Such as the random cows in Jabu-Jabu.
Yep, I hated the Spirit Temple in MQ. I screwed my game up in there...I don't remember exactly what I did, but I messed up with one of the keys, preventing me from any further progression into the dungeon whatsoever. I haven't played the game since then; I sold it less than a day after. I got the Collector's Edition from eBay with the money, a much better trade.
Haha, I actually liked the cows. I didn't know you had to shoot them with a slingshot at first, though. Kinda annoyed me for a while.
I would love a master quest too, but my doubts are in their. There is only 4 dungeons, plus the short 4 on the moon, but other then that it would just be this game over again. Mainly, the work was in the field and talking to people. And a Master Quest wouldn't change that.
