Unfortunately, this is a trend that some developers are pursuing in recent time. Especially the people who are too perfectionistic, will eventually look at their old content and would like to start from scratch. This makes it even more unlikely that this projects whose schedules is already completely unrealistic will ever be completed.wtf? Remake when the game isnt finished ?
It could also be that there is a certain hesitation to actually move forward in terms of content, because at some point, you the developer can't just raise expectations, but also has to deliver. It may turn out that a story, which is promising in the beginning, collapses in the end and simply doesn't work. For this people, it can be a good excuse to start all over again and then do "everything better".
