They've said that multiple times over the last 5 years, independently of that they also said HC would be split into HC1 and HC2 and then a proper sequel would be made afterwards, and said multiple spinoffs that were secretly in development the whole time were nearing completion.
I'll leave it up to your imagination how much of that has since come to fruition after several years.
You seem to be confusing things here. HC2 IS the "proper sequel" to HC1, though it won't be the game after HC1.
No idea what "multiple spinoffs" you're talking about. Are you sure that is something the developers said and not just mods fans were working on?
That wasn't the case at the start. Like if you look at the OP, there's still images from when the game didn't have 2D CG. I remember back in the old days when the dev blog linked to Overwhored and vice versa.
I'm aware, I have been following the game for years. I also know that they replaced the old 3D images with 2D ones and are not going back to 3D, so the talk about better renders confused me. It seemed like the comment was based on the outdated pictures in the OP here instead of the actual game, especially since the fact that all CGs will eventually be 2D has been known for years.
So, 30something out of 151 so far in 6 years????........ 25+ years to finish at this rate!!!!
No, this game will have only the "30something" girls in it, not the whole 151.
Has all the 3D CG been replaced yet or what?
Many have been replaced, though not all. There are also many CGs were never 3D due to the scenes being added after the switch to 2D.
