These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
NintendoCapriSun is not exactly an expert on Ocarina of Time, so while he does give some good advice during the Forest Temple, he also offers tips that are misleading or outright wrong.
During the Fire Temple's boss fight, SunkistJourney earnestly advises Lucah not to hang off the edge of the arena, as it doesn't work and she would just fall. Except that it does work (the edge is even climbable), and it would have helped Lucah avoid a good deal of damage.
Some fans have complained about the Sages in general, believing that the LP isn't as fun if Lucah gets too much help. Because of this, LiamSixx only gives her minimal guidance in the Water Temple.
