Oh god, this...
I remember Savin explaining the reason behind war on modding (aka apparently CoC1 has a bunch of terrible mods that, due to flash being flash, made it impossible to distinguish original version of the game versus the modded one, which caused devs to constantly get bombarded with complains over content they would never have approved and never had control over). However, I really don't think trying to combat modding and (I've heard), FREAKING SAVE EDITING is the solution.
I probably played CoC2 less than most people here (I gave up after not being able to beat a boss guarding Winter City despite having a high-level and the combat really doesn't have any strategy to it from what I've played) and while it was one of the first porn games I've touched, that also impressed me with actually trying to be more than just a quick fap game (while still being decent for quick fap game), the more I thought about it, the more I realized that it sucks in many areas and I have 3 issues per every 1 good thing it does.
It reminds me of Skyrim. Looking at it now, it's not really... the greatest game in a lot of areas. In fact, it's flawed in a lot of ways. But I still love it. And I still play it from time to time because... guess what, you can fucking mod the issues out of the game and make in into what you want. CoC2 is not the worst porn game, it has value. In fact, I don't know if I can say with 100% confidence that it's a terrible game... but it ain't a great one either.
And worst of all - it's really a hateable game. Enormous amount of futas with massive cocks, scenes ranging from great to just boring and unfun to read, combat that is awful and many other aspects you've mentioned. And, most importantly, the fact that it feels like a golden child of the devs that they refuse to be changed or modified by anyone. If devs were fine with modding and CoC2 had a proper, decent modding community that occasionally released some gems, I think the game's reputation would skyrocket. Given how pretentious some of the writing is, it creates this impression that devs don't want you to just have a fun game which provides a good wank or three. They want you to play the game in the most pure, intended way and observe the bullshit they put in, because they believe it's the greatest content out there in the porn game industry.
