What made the original Corruption of Champions stand out?
Let's take a look at something I've seen people talk about in the comments recently, transformation content, centaurxcentaur content to be specific, and compare that fetish content in CoC1 and 2, since I think that shows pretty well that the series went from being about transformations, corruption and a boatload of different fetishes in CoC1 to whatever the hell CoC2 is about.
CoC1: Like a dozen or so taur specific scenes for player centaurs, among them what I'd consider to be some of the best content in the game (Kelt/Kelly), for most of the rest of the game scenes that don't support taur bodies just pretend you don't have one so you don't get cockblocked constantly and can still play the game like normal.
CoC2: You can't be a centaur as a player at all outside of one dream, period. TaurxTaur content now consists entirely of the player character watching one of wsans copy pasted futadom taurs fucking each other and/or their harem, or having scenes like paying one of said futataurs to fuck another taur that you rescued earlier in the game.
That switch of priorities from "let's write some scenes for a player who wants to transform into a centaur" to "letting the player be a centaur is work and we can't be assed, but we still want to write sex scenes with centaurs so let's just make the player a voyeur in them", is everywhere in CoC2. There's a similar clear lack of effort/interest from the people making the game when it comes to player/npc transformation content in general, corruption content, player agency/how you can affect other characters, and last but not least what fetishes CoC2 caters to.
CoC1 had every fetish ranging from dickworms and being a walking ball of hentai tentacles to pure vanilla build-your-own-waifu content in the form of Ember. No matter what weird shit you were into, there was something there for you. And all of that content managed to coexist. (Well except for Urta.)
CoC2 cut pretty much all of the fringe fetish stuff with the exception of some one off bad ends/scenes like one drider buttimpregnation scene (and it's almost always shit that happens to the player, never something the player does to someone else), and replaced it with a hedonistic hellhole of a world (that makes the corrupted CoC1 world look repressed), filled with an absolute shitload of cuckold-in-the-closet type content like companion loss scenes, "threesomes" that are mostly about watching two other characters fuck while the player gets barely even mentioned, voyeurism (on the part of the player), sharing and an ever increasing focus on pushing an impotent feeling player character into the role of an observer to the devs self insert OC relationships with each other. (This last "issue" has taken over entire areas of the game like the wayfort and even was the reason a planned companion in the form of Einin got cancelled.)
There's also the issue that every other piece of fetish content that used to be in the previous games suffered, half of the time because of patreon and the other half because nobody working on CoC2 is into it or cares about it. The people that want more fringe scenes like impregnating people with spider eggs or breeding an incest army of goblin girls like in CoC1 get either absolutely nothing or at best can watch other NPCs do it, and the people that are just here for the vanilla romances get similarly screwed if they're not into this "free love" stuff that's omnipresent in this game, and even the two "waifu" companions, Kiyoko and Brienne, get scenes where one titfucks centaurs and the other gets raped by goblins if you lose certain encounters.
And while this review was mostly focused on "straight" content, if you're into dudes you have it even worse cause the most popular male companion got axed a couple updates ago, and now your only options are a literal cuck fetish bull and a bunnyboy who keeps letting you know that he really desperately wants to fuck your female companions.
There's load of other issues with Corruption of Champions 2, but a lot of other reviews have already talked about them.
In short, if you want a text based porn game play CoC1 or one of its mods, maybe TiTS if you're into Futa or are just really desperate.
Don't bother with CoC2 unless you're into exactly what it's about, it has some alright sex scenes from time to time but they're nowhere near good enough to justify spending hours and hours playing the game just to find a handful of scenes you like.
