What I don't really get is why he/she is trying to create new scenes every month instead of using the existing scenes.
As far as I have seen the debug mode has a variety of scenes which could be used....
He's a victim of perfectionism. He's kinda like those non hentai game devs that start development on a game, have a vision and a plan, but are helpless romantics, enamored with progress and always keeping up with the latest and greatest upgrades, updates, and innovations, so much so that they can't help themselves but to either update their game engine, add whatever new tech to the game, or outright attempt to remake everything once something revolutionary drops, cause they feel that their game isn't up to snuff anymore, especially today when progress is so insanely fast. Two examples of this are Duke Nukem Forever, which got released but only after the original studio went kaput, and Ashes of Creation, the new never-ever MMO, ETA 2600.
I genuinely believe that he feels inadequate, that everything he's made thus far isn't good enough, that he has a better vision now than anything he thought of or made before. Reason why the game will likely continue at this pace, and it will be a miracle if it ever gets completed.
