I would like to know how many addition episodes will be released before it's a full game. Too many games are Alphas or Beta's and just seem to have been forgotten by the devs. If the plan is for 18 episodes and so far we have 9, I will wait, because I always see so many itch games just stop development. And I am not paying or playing half a story.
But you can count on one hand how many Adult VNs are 1.0+, the vast majority are listed as 0.1 to 0.9, with many of them not having been updated for months. Itch should force these developers that bring out episodic games to tell us up front how many episodes they have planned for the 1.0 version. Then, if it's taken 2 years to get just a third of them done and 6 months before the last episode release, you would know it's a dead product and not waste your money.
