The longer the project, the higher chance of burnout and it being abandoned before completion.
You can be correct. However, it all depends on the developer... If it is VN story is laid out ahead of time, that helps reduce the frustration. However the designing and etc also takes time to do and that usually not planned too far advanced since it flows with the VN story. Also It depends on the developer interest. If they are please to do it without any major concern with financial or other reason(s), They may still continue with out any signs of abandoned before completion. BD already know roughly the timeline to be completed with this VN. However he may not plan the setback time.
Hopefully BD does not get too burned out. If he does, he should know when he need to take a break/vacation/time-out to recovery before continue the project. BD seems to show very strong interest in this VN and aware that he had several setback which hopefully it had help him recover himself to continue. Also he had a lot of interesting events happening in his real life in the last one or two years that teaching him more things that he need to think about while continue working on his VN as his full time.
All I can say that hopefully BD is enjoying what he is doing with this VN as well what he is doing with his personal life (I do not need to know additional details even it may be mention several time on his announcement/updates).
Have a great day and be safe...
