Well personally, its not about hard or easy, but how perfect you want your hero or gameplay to be. Example, you would rely on a walkthrough to make sure you don't miss a single scene in the game. While most of the time during replaying, I realize most walkthroughs are imperfect, like, they miss out alot of important things, or missed out afew items here and there, it is the closest to perfect since it is supposedly rewritten over and over again, like a book ready to be published.
Personally I believe it is normal to want a walkthrough, though it is easy to complete every game just by your own instinct as an rpg-er as well as a little thinking. Relying on the walkthrough really takes away a big part of the game, and many lose their interests too. It's like, using a cheat that makes you almost invincible
