Unfortunately, the snippet from the Wikipedia article you quoted exactly exemplifies my understanding of the genre tags and how I've seen them used since I was old enough to get on the Internet and read such things.

Zelda has, for me, always been an action adventure game. I don't think I'd called Zelda breath of the wild an RPG game or an ARPG game but that's because the item portion of the game felt incomparable to a game like Witcher or Diablo where every piece of your character is an item that can be upgraded.

That being said, I'm not exactly the biggest Zelda fan and BotW was like 10 years ago for me.

Yeah, Zelda was originally what I thought of when I heard "ARPG" because I grew up on the NES games. If I started w/ something later, I might consider the series "action-adventure" instead, because the definition of what an ARPG has changed somewhat. And yeah, I'd consider BotW "action-adventure" as well using today's definition, but it would've been an ARPG using the earlier definition.

There are plenty of other somewhat similar games that do qualify as ARPG today that are very different from Diablo games, like the Ys series, Gurumin, and Cross Code. The Ys series is fairly diverse, but generally speaking, gear upgrades are plot-based (find in a chest in the dungeon you're exploring) and there's not a ton of diversity, and leveling your character is very important (1-2 level difference can be the difference between a nearly impossible boss fight and a manageable one). In Gurumin, there is a fixed set of upgrades, and you combine these to get effects. CrossCode has stats, unlockable abilities, and action-oriented combat. Loot isn't really a major part of any of those games, they're too action-oriented to be an RPG, and they have too much emphasis on progression to really be action-adventure.

Those are the sorts of ARPGs I absolutely love, yet everyone seems to focus on the Diablo-like dungeon crawlers where loot is a defining factor.
