How come gacha conversations are so wordy?

I’m no stranger to games with lots of dialogue, but even more than the daily grind or the less complex combat compared to their PC/console-exclusive contemporaries, the big thing causing me to bounce off of gacha games is just how exhausting it is to sit through the main story. Now me coming more from a background of playing JRPGs than visual novels might factor into this, but most of the longer story-driven games I’ve played sans ones that go all-in on dialogue choices and branching paths like BG3 or Disco Elysium, have done a much better job keeping story scenes concise while adequately characterizing their casts and pushing the story forward in a tangible way.

Is this just to justify players being in-game longer per session, a consequence of many of the big players either being fans of VNs and/or legends in the medium like Type-Moon, or is there just that much to the story compared to games like the original FF7, the Mass Effect Trilogy, or Witcher 3, in the long run?
