I took a look at the 3 IF things, and, uh, leaving aside the fetishes... The translation is horrifically worse than the game, for whatever reason. It's barely edited MTL tier, or around that level if not worse. They're all very short. It's also mostly CG variations from already existing in-game CGs, so you don't really get much in terms of CGs either.
It's basically just a set of stuff that adds a lot more filth, which I suppose is great for the people that are into that stuff, but not great for anyone that already thought that this game had too much filth content, like me.
That said, even IF you're into the filth content or whatnot, these IF stories are not worth a single dime tbh... The fact that they're trying to get money off of this... it's the epitome of absurd cash-grab.
Ugh.
Honestly, if the games after this one get translated... I wonder if they'll even be worth it? At least for me, if they have as much filth as this game, to say nothing of the IF stories, I don't want to deal with them. XD
