Yeah, but with like 90% of the "easy" games out there you can do
something to make it harder for you (Kimahri Only challenge for FFX for example. I didn't try that one but the Tidus Only challenge actually made the game easier after I got past Mushroom Rock

). I liked how you could customize the difficulty of TWEWY from cakewalk to OH MY GOD IS THIS EVEN POSSIBLE? at absolutely any time in the game.
So if you wanted a challenge, then you could make it harder for yourself, and if you just wanted to enjoy the game's story and other things without too much hassle, then you can play at a lighter difficulty.
