I like all the backtracking in the dungeons. Its part of what works for me in these types of games. I'd be disappointed to cruise down a long hallway, picking up the keys and items that I needed to progress along the way. I know its game design to pad out the dungeon and give the player a false sense of discovery and exploration, but I wouldnt have it any other way. Im ok with suspending my disbelief for a little while. Lie to me video games. I subscribe to escapism.
If I created a dungeon to hide valuables in; I'd design it in a way to wear out would be intruders and prevent them from getting through. So in that regard I feel they have exceeed. I thought I read that the water temple in OoT was hard or frustrating, but I cruised though it with no problems. Or am I thinking of one of the Wii Zeldas?
I've also been enjoying my time with OoT (which is the second playthough after playing on the 64). The 3ds remake is so good it's almost like a new game. I should probably track down majora when I'm finished with OoT.
I put in a few hours in the first Zelda the other day and found it quite satisfying. It's very much an open world game with little direction to guide the player. You have to just push your own limits to find your way.
I fired up Zelda II today on the classic NES. It's a game I never really played much of. It's way out the box for a Zelda game but has touches of Metroid and RPGs spread on a 2D platforming frame. The music is amazing and once I push past the frustrating difficulties I think it could be quite an enjoyable ride.
If I had to pick only one series to play for the rest of my life, it'd be Zelda. If I had to pick only one game, it'd be LoZ:LttP. Hands down, no hesitation no ragrets!
