I don't think I've found anything quite as thoughtfully polished and with the general vibe/mood of Lost Chapter, and I've played a ton. Tamer Vale is close but the smut is both tame and a tiny part of the experience. Is it wrong to repay the debt in a dungeon is actually really good, but you have to intentionally screw up to start getting scenes. X-Angels is alright, if a little thin on content, Take me to the Dungeon is a legitimately unique twist on the deck builder rogue-like formula, but you only get scenes on boss fight losses and after clearing dungeons.
