So I want to ask, what is the difference between this game and playing Lustiest Lair: Expanded? both in terms of kinks and in base gameplay?
IMO this is a much more pleasant, and dynamic game.
The main thing navigating dungeons is top-down rather than side scrolling it also has more interesting dungeon encounters where you'll sometimes run into; captured girls, shady goblins merchants, item vending machines, mystery holes, etc. And receive different interaction prompts based upon your team's composition; both in class and personality (girls have personalities in addition to classes). You can also choose to simply not interact with most encounters, or sometime even just avoid battles entirely by going around them.
Girl's personalities affect what traits they can develop, and whether they'll passively decrease or increase certain trait's durability (traits can be naturally lost as well as gained). Certain personalities are better suited to certain classes, "service" is suited to support classes, "glory" is suited to front-liners, etc. and certain dungeon encounters can swap, alter, or reverse a girl's personality (if the correct option is available and luck is on your side.)
There's also this whole 'crest' mechanic within this game where girls will develop 'Crest of [blank]' that alter their stats but also (potentially) change the type of orgasm (mental break) they have when they reach 100 lust. Also reaching 100 lust makes them orgasm instead of die.
Recovering girls isn't raising them from the
grave slave yard, but going on a mission to the dungeon where they're being held, and it actually gets easier the longer the girl has been captured although the girl becomes more corrupted/cursed the longer you wait as well so it has a much more dynamic mix of things. This combined with the more dynamic dungeon exploration means that recovering girls is delicate balance of risk/reward rather than just an expenditure of resources.
AFAIK the only way to
permanently lose a girl in Ero Dungeon is to dismiss or abandon her. Though sometimes they can get pretty messed up by the curses/forced class changes, sometimes it can also be beneficial because they'll get items that will boost their efficient when working at jobs. Certain traits will even boost a girl's stats if they're wearing a lot of cursed items.
Girls can work jobs. You can set them to work any of the major structures to improve that structure's function; bunny girls boost lust reduction at the tavern, pony girls have new girls from the stage coach start with upgrade points, maids boost starting moral from the barracks.
Also in the porn-side of things, when girls get grabbed there will be little animations that play rather than just flavor text, and AFAIK every enemy who can grab has a unique-ish grab animation (there are several variant enemies like tanks of white, pink, or black fluid, which share an animation but apply different effects during grabs).
All the girls can equip any of the outfits or items, only weapons are restricted by class, and some items will just be nudity. I have a Mage who gets a nearly 100% damage boost from her "Cloak of Visibility" due to being an Exhibitionist, with the Crest of Exposure at 100% and a Warrior who uses stacks an Arm Binder Weapon, with a move-restricting brain wash visor, exposure underwear, and crit gloves to restrict her to 1 move that normally does 2-5 damage but instead does like 10-25
TLDR: This game is better.
