I think that L&P will finish this game because he is stubborn ect and does not want his first VN to be a failure,in his eyes.
It will be a train wreck ending but L&P will hail it as a sucess.
I'm saying that there's a problem with his plan, not his thinking.
No matter what he thinks, based on the current state, this game can't end, unless he gives up on it.
As I said, characters are constantly being added, and at least 10 characters have independent update numbers.
Even if he were to complete only Sophia/Sam route, it would take at least 1-2 years. (If he were to compress the story to the extreme.)
I think the Sophia/Dylan route is still not on track, so I think it needs more updates and more time. (Again, if Sam's story is compressing to the extreme.)
The characters become more important as they get closer to the end, and they will inevitably come to a point where they can't be compressed.
If he doesn't reduce the number of characters, there will inevitably come a day when 1PD will be 3 or 4 years instead of 2 years.
Therefore, regardless of his thoughts, this game cannot end.
