This series has a long history of scrapped versions, partially due to how they evaluate things and have a lot of creative freedom. For the record, REmake 2 was not scrapped, though the team did decide to rework stuff, but this is closer to what they did with RE7's final version. RE7's opening hour was scrapped and redone at one point, in a similar fashion the Raccoon City segments of REmake 2 were scrapped and redone at some point. This isn't a whole scrapping/rework, more a... Normal game development rework. The reason for RE7's and REmake 2's openings redone is a similar reason though they're very different in content, the team thinks the beginning of the game being memorable is important, and in both cases they thought they could do better than what was nearing completion, so redid it to up the quality.
