My favorite part is when people say that Mario and Zelda games are the pinnacle of stagnent gaming. Because you know, they totally don't try to make some kind of significant change in each entry.
-Wind waker, definitely the same as OoT
-Majora's Mask was just a shameless sequel.
-Twilight Princess, definitely the same as Wind Waker
-Skyward Sword, yep just a remake of Twilight Princess obviously.
-Super Mario 64, basically the same game as Super Mario World
-Paper Mario, same game as Mario 64
-Galaxy, duh its 3D, obviously a shot for shot remake of 64 also.
If you can actually believe these statements realistically you either have never played the games or must think that pretty every game in existence is just an enhanced version of Pong.
People love to say that Nintendo repeats themselves all the time while completely ignoring the fact that they really only repeat themselves about 25% of the time. The rest of the time they at least add something significent to the gameplay.
If you disagree with me I'd like to hear where Nintendo milks a franchise as hard as CoD, Guitar Hero, (Blah Blah Blah) Saga (by Kings), or Madden. Really the only thing that comes to mind is the New Super Mario games.
