Why?For exploration to be a key pillar of the game, then it needs to be gamified in some way.
What's the reasoning behind this claim that if its not gamified, its not a key pillar. Actually, we also need to get the definition of "Pillars" out of the way.
The three pillars aren't meant to say that they are weighted equally in terms of importance. They are the categories of the adventurer's activities. You fight, that's combat. You sneak, that's exploration. You talk, that's social interaction. Nowhere in the game, though, does it say that pillars are meant to be measured against each other or that they should be distributed equally.
TL;DR pillars are categories, not key aspects of the game. They're just used to define what the players are doing in a broad scale.
