I see, and in this case I'll strictly compared it to 2018 list. As for whether 2010 list is better compared to 2018 or not, well it depend on the rank here. But overall I would say that 2010 is better though because most of the score for the VN that was released in 2010 is higher if we compared it side by side (2018 releases did have less VNs that receive average score 8 from VNDB), at least if I based it on my list here. On the other hand, there's a lot of good release that I didn't add to my release simply because it's censored (Baldr Force), MTL-ed (Your Diary and Fortissimo), and only a fandisc (Fata Morgana). There's also some good releases that I didn't add simply because it's not my taste here, such as Sakusakura and Suki Suki. So objectively seeing, I would say that 2018 is better if we talk about the number of releases and quality, although each year did have advantage and weakness though.
tldr - From my list 2010 is better, although if we look at it objectively 2018 is better. So I guess we can say that it's a draw here, although it may change in the future though seeing that VNDB average score will always fluctuated.
