While I know there are games on Unity with manual saves, I don't think I've seen one where you can save during the dialogues, not sure if you can make skips as fast and convenient as in renpy as well. Oh, and what about rolling back? I wouldn't care what engine the game is made with if it literally didn't make player's experience that much inconvenient.I've already explained this before,just look on the previous page with comments!
PS: Happy New Year!
I mean it was fine just playing the game, until I decided to see the difference in club scene in season one depending on if anna/matt don't go there. Had to load a autosave before that, skip a lot of dialogues, check the scene and repeat, it was just way too much time for as simple as that. Would literally take me half a minute in any game in renpy. And, if anything, getting more players would help the game, and renpy does exactly that.
