I would mention the old Ail-Soft games but those are pretty fucked, and probably don't run easily on modern systems anyway. I will mention God of the Dark Night if you can deal with an untranslated and difficult to OCR game:
[KI-SofTWarE] God of the Dark Night RE:FinE / 黒夜神 RE:FinE ~堕ちた肉奴隷達の徒花~
And, while a bit shallow, the spiritual successor is alright too, and apparently in English:
DiabolicaL ModifieD WifE
They're both essentially visual novels with a few branching paths (Diabolical Modified Wife has a weird gambling game element to it). With gameplay, Crossing Knightmare was pretty good, and a kind of tightly scripted RPG element to it, honestly I've never completed it:
CrossinG KnighTMarE
It's nothing much:

Also, check out
this guy's thread here, he shares 3 lists of BE games he's played, plus WG. There are a lot of repeated things that have already been mentioned here, but there are some rarities there.
Weird, when I quote your post it shows you listed Crossing Knightmare too lol. Salvor Deep definitely shows promise, one to watch. Aruna is surprisingly very fun. Haven't played Descendants of the Forest, but I like the look of it and I'll be trying it. Good link there too.
I know text adventures aren't the main thing in this thread, but I really started hunting for BE games from Corruption of Champions (and to a lesser extent later games, and yes, futa, etc., the other games I listed have scat even),
Slave Maker 3 (Aerith), and Nimin: Fetish Fantasy (only playable on furaffinity, and is a flash game), so I guess if we're talking all-time faves, I'd be remiss to leave those out of my list. All got flaws though, I wouldn't say there's been a game I feel like is 'flawless' by any stretch.
