Because of this video and Arin Hanson.
But also because it has some pretty major flaws and is generally a pretty boring.
Best Dungeons is debatable - TP, WW, and LttP/LbW

Stamina was a horrible start to what they really wanted to do which is seen in BotW
I just think this game was clearly the test for BotW
