It has a little more gameplay than past telltale games with its dispatch sections (a bit of strategy, deciding which heroes go on what calls), but otherwise you are right, it’s a fancy choose your own adventure game. They have done some interesting things with superhero tropes so far (e.g., superheroes working out of a corporate call center), but it’s a bit early to tell if they’ll subvert some of my expectations for the “final boss”.
The newer zelda games are interesting since you can see how the world has changed between botw and totk, but on the macro scale you’re definitely right. Most zelda games have formula of “all is well, bad guy appears to threaten realm, link saves the day, back to normal”. BOTW was an interesting way to change that formula - hyrule isn’t restored after you beat ganon, but things change with new settlements being formed and so on in totk
