Uff, Depraved Awakening is simply amazing. For those who don't know it, it's from the same creator of City of Broken Dreamers, both chef's kiss.
But to be completely fair, Depraved Awakening was finished ages ago, so anyone who wants to play it can do so in one sitting and without having to wait for updates. Also, this VN never went under a rework. As much as I liked it, certain models (like the blonde girl's whose name I can't remember right now) could look veeeeery veeery odd and outdated in certain scenes (Her nose looked as if it was made of smooth plastic, with no shadows on the sides of the nostrils).
Also, Depraved Awakening was very very short. Even CoBD is a shorter AVN as well (the next update will be the last one, if I'm not mistaken). While this can have de advantage of completing a game faster, it also means the story and your interactions with the LIs will be shorter.
Summer's Gone not only is going to have a longer main story, but your personal stories with each LI/friends have the potential to have more depth as well, precisely because of the length of the VN.
So far I haven't seen meaningless dialogue. Small talk can be pretty meh sometimes in any VN, but it also helps you to add friendly banter and friendly interactions with others. For example: In BaDIK, Bella shares her story as member of the sorority OMG, and then it's never mentioned again in the future. It might be consider pretty meh, meaningless and irrelevant, but her having this dialogue helps you know another side of her, and helps her build her relationship (whether is romance or friendship) with MC. Filling dialogues with only 'important' stuff or Chekhov's guns would get old pretty fast, imo.
