RE9 is great for the first playthrough, but really falls apart on replays. RE3R actually holds up on replays. Not a great game, but it's definitely more enjoyable on subsequent playthroughs. As brilliant as Rhodes Hill is, because the zombies follow very specific routines and paths, it becomes boring on replays. Leon's section is even worse.
I think by and large that's the issue with the latest mainline entries. RE7-RE9 strengths lie in their first playthroughs. They're very good at surprising you and creating a sense of terror. Each game is like a box of tricks. But once you've been subjected to all the tricks, the games start to fall apart on further playthroughs. The thing about the Remakes however is that the team that make them focus a lot on making the gameplay fun, so they hold up on replays.
I can't help but wonder how many critics who gave this game a 9 or 10/10, wrote their reviews immediately after their first playthrough. Because if they did then that would make a lot of sense. If someone gave this game a 9 or 10 after multiple playthroughs, then I really don't get how they arrived at that number.
