This month was almost a no-brainer... while there were some halfway-decent charage releases, there weren't any that made a significant impression. I'm afraid I don't have time to read Giga's newest half-hearted-but-pretty-looking charage (work is busy) and I haven't actually played any VNs since i finished Ninki Seiyuu last week.
Silverio Trinity is VN of the Month January 2017. Normally, I wouldn't name a sequel as VN of the Month, on principle. However, in this case, the game itself warrants it. Silverio Trinity is one of those rare sequels I could actually conceive of standing on its own, because even when I extracted my prior knowledge of Silverio Vendetta, I still felt that it was an enormously enjoyable VN. The only point on which it doesn't stand on its own is in background knowledge about the Esperanto and the Great Apocalypse that is only infodumped in incomplete form in Trinity. Of course, not having full knowledge of the events at the end of Vendetta's path in Vendetta is a handicap, but not as much of one as it would have been with another game, lol.
For those wondering about VN of the Year 2016, I'm still reviewing the candidates... I've narrowed it down to three potential winners: Tokyo Necro; Karenai Sekai to Owaru Hana; and Amatsutsumi. The most unlikely of those is probably Amatsutsumi, despite its feels (I knocked Floral Flowlove out of the competition last week). For those who complained to me about the fact that I'm not considering Senren Banka or Gin'iro Haruka, I actually have solid reasons besides personal tastes... I just don't feel like making a wall of text to explain the precise reasons why Gin'iro isn't in the running and I never really even seriously considered Senren Banka, lol.
Edit: Keep in mind that VN of the Year is the competition I spend the most time on every year, using up a minimum of the first two months of the year each year since I started, lol. Not to mention that 2016 was one of the best out of the last ten years in terms of high-quality releases (though the ones that weren't high quality tended to be singularly awful).
List of VN of the Year Winners so far
Nanairo Reincarnation (2014)
Kikan Bakumatsu Ibun Last Cavalier (2015)
Again, 2015 is probably the single worst year for VNs out of the last ten, and so Kikan Bakumatsu is actually lower in quality than several releases from both 2014 and 2016, so I almost didn't name a VN of the Year 2015, lol.
