Do you have any recomendations of other games that do this?
i feel exactly the same about this game, and i wanted do know other games that have this settings of corrupting the city.
Well no, not in the way this game does it, but there are a couple of games that do something similar, but it is always either left to you as the player to push for things going down that way in order to achieve something of that sort or it is limited to a certain game/story/quest area with a specific set of circumstances that purposely break the rules of what your character would usually do (like forcing your character to walk around naked, have sex when or where she usually wouldn't, etc.), which i like to call "the closed box" area (these can be even better than town corruption if done well).
For example there is a now long forgotten little game called Mystic Mine that did the whole town corruption thing but it was limited to everyone eventually trying to bone the MC since i don't remember there being any other female chars around so that is sort of the extent of it. Many other games do this sort of "corruption" if you can call it that, but it mostly only ever affects the mc and a few other side characters at most.
Early Acerola games had some of that where you could transfer your lewdness to the side female characters and make them get into all sorts of trouble, but again it's limited to that.
Dragon planet had one of those closed box areas with specific rules like the slave town which was awesome just because it broke the rules entirely and made you operate by a whole another set of rules for a while. Ice knight Icelina also had something like that only a lot more involved.
There is also one really old VX game with CGs made using 3DCG called RE:Anise2 (there are of course also the original Anise and RE:Anise) that had a particular end game segment relevant to your question called the slave island. It basically flipped the entire game on its head and made both the MC and her best friend into slaves forced into all sorts of debauchery (that segment alone had so much content that it might have been a separate game), and to make things better once the MC and the said friend escape they can even later on decide to go back of their own free will (basically all that fucking of men, animals and monsters did a number on them permanently), and at that point you can come and go in and out of that area whenever you want (it does ramp up the MC's degeneration level as it isn't forced anymore).
The best example though is one particular game which never really caught much attention called Apprentice Moby which did it in a really organic way where the manner in which you completed quests and interacted with the other characters basically affected how things would end up for both you and your friends (some of the outcome requirements are really obscure though). If you wanted to see them fuck/getting fucked by pretty much the whole town you could totally end up with that and even get involved yourself even though you brought about the whole situation. It has some of the best constructed H scenes ever with many of them reacting to both your state and the state of your friends (being naked, covered in cum, pregnant or even having a vibrator shoved up your pussy changes the dialogues completely and sometimes even the flow of H scenes). It also has the best close box segment with the Work Appreciation quest (which is repeatable after the first time). Basically one of the MCs friends who is the heiress of a large merchant guild decides that she wants to uh "reward" the many employees of her company and of course drags the MC into the whole situation. The catch here is that the said friend seriously stretches the whole concept of who, where, how and why she should reward (entirely on purpose of course) which in turn extends the closed box segment onto the entire game area making you able to pull just about anyone and everyone into it if you so desire (it's totally freeform). It is freaking awesome and i have never before seen a game offer so much choice in how you want to do things.
So yeah these are just some examples from the top of my head. There are many other games that make your actions affect your surroundings in this or that way, but not many that do it in any serious capacity or the way Cornelia does. Hell that is why i always said that the only flaw of Celesphonia is that it doesn't really show nor make you experience any of the consequences of both your or the enemies actions (the hypno school part of the story was a good try but it is too short and doesn't really go deep enough). It tries to show you how fucked up things can be when they take a dark turn but it never has the balls to actually go all the way by altering either your surroundings or the way you do things in the wake of an invasion by what is basically a horny interdimensional Cthulhu.
