I've been going through several of the more recent Zelda 2, Zelda LTTP, & OoT romhacks and of them I found these to be quite good:
>Interconnected Strongholds - LTTP>Allhallows Eve - LTTP>The Shadow's Fall - LTTP>Amida's Curse - Zelda 2>Master of Time - OoTI really prefer the dungeon design in Interconnected Strongholds/Allhallows Eve over any other LTTP romhack currently - same author for both Letterbomb so I think that's a name to pay attention to. Feels like stuff Nintendo might actually do dungeon & puzzle wise. And they have a good degree of challenge too. The Shadow's Fall, another recent LTTP hack also had good dungeon design but it was on the shorter more atmospheric storytelling side. Starts hard though - gets much easier after first dungeon. The first two though - I'm glad we actually have good LTTP romhacks finally that aren't pure Kaizo like Parallel Worlds was. Amida's Curse is just really strong all around - lots of dungeons and a big world to explore. Good balancing - different spell order but it works. Master of Time is just a very very impressive romhack all around - only real issue is the author getting bored and making those endings - there is a Malon hack of it that fixes the ending but I have yet to play it past the opening so I can't comment. I also need to go through Ultimate Trial which is supposed to be really good as well.
