Well, if that's the case I hope his release schedule will be shortened to 2 months per update.
I don't care how good the game is (and you all know how much I love BaDIK) but 5 or 6 years to fully develop an H-game working full-time would seem absolutely unbearable to me and possibly to many other fans. You can only catch people's interest for so long.
2024, 2025... Damn. I'm not even sure DPC would be able to keep his own commitment and interest in the game all that time.
EDIT: On second thought, I don't buy his statement. Sorry but I don't. I'm sure DPC laid out the structure of the game before he even started working on it. He wrote the story and knows exactly how many updates it will take for him to wrap it up. Maybe instead of 12 he will end up requiring 13? That's possible. But I don't believe for one second that he doesn't know whether he will be needing 12 or 20 updates. This is DPC we are talking about, not Icstor.
Given how big this game is becoming, update times are far more likely to get longer than shorter. Even if you don't take the rendering time into account, there's still the posing, lighting, coding, writing, animating, etc, and that probably takes the longest amount of time.
Obviously we're all on the player side of the game and don't know what DPC's plans might be, but I personally find it hard to see how this game goes to 20 episodes. The first 4 episodes have already pretty much wrapped up the Maya/Josy arc, the other main girls can also apparently have their paths shut, and Quinn's plans seem like they're about to come to fruition. That last one is also what seems to be the main underlying story of this game.
It might seem like the story is all about getting girls and joining the DIKs, but that's what movies often feel like too and then you find out there's other stuff going on that the lead character will get swept up in and the story is really about that whilst also trying to get the girl. It feels to me like this is the case, and so how that could stretch to 20 episodes when it's moving at such a swift pace already is what's hard to see right now. We've had a good first act/season and it feels like it could easily be wrapped up in 3 acts/seasons.
