Alivaril mentioned the "top quests" on the site in the thread for his new quest, and it got me curious. After checking, I noticed that Divided Loyalties is doing really well by most metrics and might be n°1 quest on the site soon-ish.
Sorting by views: Divided Loyalties is either n°2 or n°3. The Long Night + sequel might be enough to take the n°2 spot by a bit if you count them as a unit. There is a sizeable gap separating it from the n°1 spot, which is held by A Sword Without A Hilt (a quest with a much small playerbase, but an insane update rate). However Divided Loyalties is a lot more recent than the other top quests, so if things continue at this rate it'll outpace them both! FYI, Divided Loyalties started in 2018, while A Sword Without A Hilt started in 2016 and Puella Magi Adfligo Systema and The Long Night both started in 2014. The 5th and 6th position quests (Dynasty of Dynamic Alcoholism and Marked For Death) both started in 2015 and don't look like they'll be overtaking the others soon.
Sorting by replies: Here
Divided Loyalties is secure in its n°2 spot, with a massive lead that is steadily widening. It's further from beating ASWAH than in the "views" metric, but it's also advancing a lot faster so if things don't change it should overtake it soon-ish too. The general ranking doesn't change that much, although we see some dead quests like Paths of Civilisation come back into the rankings (it's n°5).
Sorting by first message reaction score: I don't like this metric, because many quests have a first message that's a bland informational post or un-fun character creation, and that therefore gets fewer internet points. Indeed, here we see lots of quests that started strong (immediately start with a very fun chapter) but which are absent from the top ranking in other metrics - for example the n°1 quest is "Battle Action Harem Highschool Side Character Quest (No SV, you are the Waifu)" which absolutely crushes the runner-ups, Rhunrikki Strollar (n°2) and
Divided Loyalties (n°3). This also applies further down the rankings: the impressive art quest Terrene Spire is on the first page, as is the long-dead Orochimaru quest Shed Skin. This is also affected by author "fame": the number five is UnwelcomeStorm's very short quest, which never went far but surged to a strong start with all the Worm fans he brought from his fanfics.
By this metric Divided Loyalties probably won't be n°1 anytime soon, unless every reader goes back to react to the first message just to achieve that
EDIT: To be clear, when I say Divided Loyalties will be n°1 "soon-ish", I mean "in several months, assuming the current breakneck pace continues". ASWAH is absolutely huge, updates three times a day, and has a two year head start. Divided Loyalties progresses faster, but every hiatus lets ASWAH increase its lead by a fair bit.
Not that this is a competition, of course. I follow both quests, and like them both quite a lot.
