People moved to SVS/Aicomi, but even those are not getting much due to how difficult is to make mods and people refusing to move from KK.
Quite a shame, but extremly typical of Illusion/Illgames! Honeycome runs rather splendidly for a game from them and is relatively compact sizewise. Given that the graphics quality is a lot better than KK too, they had a potential winner here.
But no, they made mod making, which is very important for their games, a chore. Logically the fans are reluctant to shift to HC/SVS/AC, because there are few mods and it is difficult to make more. Aggravating this is the fact that esp. Aicomi has a distinct lack of features the fans know from earlier games and is finicky in play again. No comparision to how nicely Honeycome runs.
The situation is similar on the HS/AIS/RG side of their games. Roomgirl has the best 3D looks out of the box, runs rather smoothly, but they dropped the ball there too.
