i found Twilight Princess easier than Wind Waker, though i could just be saying that cause i haven't plaayed Wind Waker in a while, i've only beaten it twice, i beat Twilight Princess 4 times, i'm not that big of a fan of Wind Waker, it was awesome don't get me wrong but the idea of traveling by sea just ruined it for me cause as soon as i found out about that feature in the game i lost all hope of there ever being underwater travel, and i was sadly correct when i progressed, i loved underwater areas in Zelda games cause i love swimming, in or out of gaming (though i'm still one of the many people that has a grudge against the water tempels)
I though both were easier. But WW was easy than TP. Well I guess bcuz WW is cel-shaded graphics and TP is like realistic graphics. But I played TP first then came WW. I guess WW was easy but I'm not finish with it yet.
Twilight Princess was freakishly easy. The bosses, most enemies, most dungeons, the overworld, the upgrades, and the pieces of heart were all quite simple to undertake. Wind Waker on the other hand was for the most part easy, but a lot of the sailing elements made it complicated. I havn't played enough Phantom Hourglass yet to truly judge it, but it seems uncomparable to console titles.
Well I have to say the WindWaker was easiest, for me, because one, I am STILL stuck in TP, and PH was a bit hard, because of the dungeons, in both TP and PH...plus, the only thing I found difficult in tWW was getting all the Triforce Shards...
