Yeah, playing after being convinced is fine, but to find out if something you like/dislike is in it or not...
Unless it is a spoiler, the only reason not to answer would be if it was too much work to find out.
In this case, how many of them are animated? Well, some of them the "animation" is just some frames that change as the text progresses, others it is actual animation. Last I checked it was mostly the first, but I didn't restart the game so maybe they were added later and I missed.
And mechanics-wise just playing a demo it also is not always the best way to check things out if you like, as weird as it sounds.
My own example, a demo for Monster Hunter 4 Ultimate. That is the core battle mechanic, you are dropped into the map with some items and an armor and told to fight a monster twice your size.
That, for me, was a bit boring.
Then my brother bought the full game, because he had played a pirated version of the wii one and knew the real game.
And I played it, the real it, for a bit. As in not just the demo but the hunt for ingredients for making your healing potions, how you forge weapons and armors and upgrade weapons from pieces of different monsters.
I learned the real meat of the game, not just the playing of it.
So yeah, bought it, then Generations, then when I got a Switch Generations Ultimate.
And for those games with a good gameplay, maybe even art, but that are story-focused and the story is bad...
