First, some statistics. Here's the chart of total number of VNs, number of listed VNs in this blog and number of blocked VNs for the years 1991, 1992, 1993, 1994. Number won't change significantly since for the moment these are all the VNs that vndb.org has for the noted periods.
Foreword: This is Keno-san's scenario. He did not have much experience when we was thrown to produce scenario of the game that we know as Love Potion in two months time. Critics buried the game and that's why there was much more care in producing next game scenario - that was DESIRE, the game that I can't praise enough. The next year Keno wrote scenario for EVE burst error and on the wave of popularity move to legendary Elf company where he kept working on EVE franchise and created another masterpiece YU-NO and then left for Abel company. He created a lot of wonderful scenarios after that but we're interested in Xenon ~Mugen no Shitai~ scenario. It was developed after DESIRE but prior to EVE. So it was the golden age for Keno and he was experimenting a lot, trying to further develop the already complex DESIRE structure. This resulted in Xenon -Phantom Limbs-.
There aren't masterpieces this month, but if it comes down to the impact Ai Shimai ~Futari no Kajitsu~ is the winner, but only its original version, not the dreadful remake.
Another bakage from Alice Soft. I've no idea how to write reviews of such games. Guess a structured review won't go since there's nothing to discuss - there's no serious story or theme or interesting characters or anything worthwhile. All it has is bakage action, ero CG and lowest quality "variety" humor of stupid illogical events, not even sensible one. So I guess I'll just stuff it with images with some comments.
There aren't masterpieces this month, but I can't let an average bakage to be the winner, so I nominate Shinsetsu Ooedo Tantei Kamiya Ukyou as VN of August 1994.
Year 1993 was... strange. Most of praised games of the year were blocked by me due to nukige nature of the games. Those games include Kawarazaki-ke no Ichizoku, Rance 4, Viper series, NOVA, Ayumi-chan Monogatari, Kindan no Ketsuzoku. And a lot of quality representatives that I don't even want to mention here are purest brainless nukige. It really looked to me as if the world got mad after the strict censorship of 1992. The number of VNs that made into my list slightly decreased from 4.08 in 1992 to 3.75 in 1993 due to increased nukige tendency.
Foreword: I've played it in on a whim. Looked into synopsis and just could not believe that Cocktail Soft would do a full-scale fantasy eroge with rapist hero as protagonist. Fortunately, my belief in this old company prevailed.
Youjuu Senki -A.D. 2048- is not really a masterpiece at all, but without strong competitors I find it entertaining enough to be called VN of the September 1993.
A very weak month. But if choosing among ero-centered games, a mahjong game and an animated little masterpiece, I'd choose the last one. Houma Hunter Lime Dai 03 Wa is VN of August 1993.
Foreword: I do not believe in AliceSoft. As for me, they can only do that pornographic rapist Rance series over and over. So any work outside of Rance franchise is of interest to me to support or demolish this statement.
Cosmology of Kyoto publication month is unknown, so I just put it to February that had relatively few titles. Cosmology of Kyoto is the only masterpiece of February 1993 and thus VN of the month.
