They're okay mostly, also we don't see them often. It highly depends on the game itself. I like Cursed Covenant mini games, for example (which is pretty much just a touch simulator). But if it's puzzles... some are really fucked up xP
Not really. I remember it did happen to me like once or twice when I just left finishing a single route because it felt like "It should be a canon". But mostly I prefer to give the author's work more attention, even just out of respect
I just hate all gacha games. For me, their maximum interesting time is 2-3 days. Anything further just turns into empty grinding you'd most likely fail to do because it's pay-to-live. Even with interesting characters
I prefer more choices, but of course it should be something more balanced. One choice every 30 minutes can become very boring if the writing isn't good.
