I said nothing about whether or not other games can hit the same exploration notes. I acknowledge that apples and baseballs are both roughly spherical and similar size and weight. They can both be thrown. I acknowledge that Risk and Axis and Allies are both about war. They're both board games that have the world split into regions and conflicts are resolved by rolls of the dice.
Same with narrative games. They have superficial similarities and at a 10,000 foot level share some things in common. But people constantly interject how narrative games work into D&D specific threads and I don't see the point. What, specifically, does it add that hasn't already been said from the perspective of D&D or similar traditional games? I talk about how I set up scenes, how I run NPCs, how I give people choices on the direction of the campaign, how I have varied encounters that frequently don't involve or can avoid combat.
It's like going onto a BitD thread and talking about how D&D is so much better because we track HP, AC, spells and saves so we have more tactical combat, how it's so much better to have detailed inventory because it forces people to plan ahead. The goals of the games are just different and other than a handful of similarities which apply to virtually all RPGs I don't see that there's anything in common.
