Basically, the idea behind this change is to make newer VNs more represented in the rating. I'm not sure how I feel about this, honestly. On the one hand, it makes it easier to find some less known but interesting VNs. I noticed that a lot of VNs that suddenly appeared in the top-25 were already on my wishlist. On the other hand, I feel like the troll voters will downvote these less popular VNs into oblivion, and in the end, it will make ratings even less useful than they used to be.
