I Haven't used the Seikah Stone yet in Skyward Sword, but I know of some people who would need it. I pride myself in being more of a puzzle-solver,, so I try not to have outside help. However, I don't think having a Super guide isn't necesarily making the game too easy. In reality, it makes it more user-friendly and appealing to a wider demographic. Gamers who want a challenge need to only ignore the help.
