:facepalm: Then I guess Nintendo should of waited to the 3D gaming era to make games then. Seriously, just because of how certain characters look in-game, doesn't mean that's their actual "canon" appearance", that's why I said "non-canon" cause it may be their representational appearance in-game, so it is "canon" in-game but not in the actual story of the game, that's what the artwork is for. So, let's say for example, just because Agahnim had a green robe in ALttP, does that mean that that is the exact the color of robe he actually canonically wore? No because he clearly had a red robe in the ALttP artwork. Heck, he even had a red robe actually in-game in Oracle of Seasons. You shouldn't determine what characters canonically look like based on how they are seen in-game, especially if the game is 2D and has limitations to character appearances, now that is "wrong", not what I said. I'm just being honest here.
It probably does have more to do with so that Link would stand out more I guess.
