The people who buy these games are the problem, not illusion.
If people would actually stop buying the bland garbage and buy the good games, illusion would be forced to stop making bland garbage.
AA -> AA2: Not much difference, but people bought it, so illusion got away with it.
PlayClub, Honey Select, PlayHome: This set of 3 games is almost the same (just some settings changes etc.), and people bought it, and illusion got away with it.
Sexy Beach Premium Resort: That one... I still remember, but given that there is no sequel or "similar game", it flopped, finally.
Koikatsu -> Koikatsu Sunshine: KKS is actually a downgrade in some areas, at best the whole game is a "sidegrade"... but people bought it, and illusion got away with its nonsense. (Guess what KK3 will be... another sidegrade, gg, you fucked yourself.)
Emotion Creators: Flopped again, because it was a useless pile of garbage with even less gameplay than the "Scene Selectors".
AI-Shoujo: Was fine, but illusion did not add Free H, so that they can sell it as "Honey Select 2" later... and people went and ate the shit that illusion served them. (At least AIS aka AG4 had some gameplay and new graphics and so on.)
Honey Select 2: The Free-H from AIS, but you now have to pay for it, zero gameplay, just another bland scene selector... and people bought it.)
Room Girl: Another Scene-Selector, with improved graphics, better performance but problematic modding (for now). I dont know how the game is doing, but at least they did not sell us the Free H as a seperate game again.
So, what is the conclusion:
People need to stop buying the garbage illusion makes, so that they stop making garbage because they dont get away with it anymore.
If people buy the Free H of AIS for 70$... they are beyond stupid, signaling illusion that they can do such stupid things.
People bought KKS, yet it is nothing more than a DLC for KK.
RoomGirl is the result of "illusion getting away with it" for 15 years... and only the players to blame. (but it could be worse... see the "Custom Maid" stuff.)
So, what will the next games be?
- Koikatsu 3, another bland sidegrade of Koikatsu.
- AI-Shoujo 2, but with the graphics from RoomGirl. (Alternative: Sexy Beach 6 with this graphics.)
- Maybe some garbage VR game in between, who knows.
