When I joined the Yukkuri fandom, one thing I noticed was that there wasn't really a well established or widely agreed upon list of really good works. Sure, everybody says "Read everything by Kiriraitaa and Takumi", but what comes after that? Sorting by score/favcount is absolutely useless for finding stories thanks to the low usercount of this place (it's kinda useful for finding individual pictures though). The closest thing I've come to a "sort by quality" option on this website is sorting the pools by post count, which don't get me wrong, almost every high post pool on this site is decent to great. But it misses out on a lot of great smaller stories. And don't get me fucking started on trying to find the best text-only fanfics. With that in mind, and to help newbies to this place (cause god knows the Yukkuri fanbase is on life support), I've thought about starting a list of what's considered the best/most recommended Yukkuri works.
I've found two websites (blog.livedoor.jp/yukkuriplace_anko blog.livedoor.jp/yukkuri_anko) that has a list of its 20 most favorite Yukkuri stories. I mostly agree with them, and think they would be great starting points for this list of our own. Here's what they have in no particular order, other than the same artists being grouped together:
[Kiriraitaa] True Happiness
[Kiriraitaa] How to Increase Yukkuri's Happiness
[Kiriraitaa] Common Crying Yukkuri
[Kiriraitaa] House Yu
[Kiriraitaa] Between Studies
[Yuudoro] High Grade Pet Shop Reimu
[Yuudoro] Stalk Amputation
[No.36] Yun Donuts
[No.36] Crispy and Tender Maricha
[Machiyu Aki] Back Alley Beating
[Machiyu Aki] Yugyaku Education
[Oppai] Room Filled with Happiness for the Little Ones
[Ame Aki] Yukkuri's House
[Yukkuri Jenga] Kotatsu Invasion
[Mecha Aki] A Marisa Diary
[Tenpura Aki] Argue it Easy
[Stake Guy] I don't even know what pool this one is
[avr-18g] Finding a New Home
[36dc] Factory Field Trip
[Suzume Aki] Human Extermination
[Ea Aki] Reimu and Mommy's Clothes
[Aquarium Guy] Yukkurarium Family
[D.O] Anko 0467 (Domesticated Yukkuri Reimu)
[Zenra Aki] Anko 1160
[Gesu Aki] Yukkuris in Town
[Yohaku Aki] Forest of Death
[Kimo Aki] Little Stray Marisa
Of course, if you like one artist's work or artstyle, feel free to explore the rest of their library.
This certainly isn't the be-all-end-all of good Yukkuri stories; there's a handful of stories on this list that in my opinion aren't great, it's excluding a few of of the better works from certain artists in lieu of not-as-great works (for example, I think [Kiriraitaa] The Baby Marisa and the Shelled Marisa (http://yukkuri.shii.org/pools/294) is one of the best works from Kiriraitaa), and it's missing Takumi and Big.g entirely, who are pretty much the only artists with good artstyles still active in 2017. Like I said though, it's just a starting point, made to be amended and added to.
Personally I would add:
[Machiyu Aki] Abyuse Counselling
 Removal of Marisa's Accessory
[Ammo] Yukkuri Family from the City
And if we're including games like that one list with SimYukkuri:
If you're looking for more stuff, looking at anything under the "Translated" tag is pretty reliable, since it means it was so good somebody took the effort to hard-translate it. This usually skews far more towards older works though since the new method to translate is soft-translating via notes.
As a side note: a lot of these pool names don't even begin to resemble the actual Japanese names of the stories. We should probably fix this.
