Although I'm currently getting stunlocked by work and school, so my writes has been a bit slow as of late.
Can sympathize, good luck with those!
It'd be neat to see a spreadsheet detailing complaints to actually see what most people are mad about, but strictly sticking to this thread would have very biased outputs. But off the top of my head the top three most repeated grievances are:
Savin's total ineptitude
The Observer's Purple Prose Rage Bait
The perceived focus on Futanari
Special mention: SomeKindOfWizard's total obsession with NPCxNPC content
Oh, it's the CoC2 Thread Cycle, SKoW's shtick has been pulled up recently enough. The thing with this thread's complaints is that they match the game's development in how they're usually consequential to whatever's going wrong.
Savin's repeated instances of getting his head in places he probably shouldn't and not getting his head in places he really should are a long standing fact the game's development has to deal with. Tobs has been a regular contributor and he can't pull that 2013 4th Edition Cambrige Advanced Learner's Dictionary of English (avec CD-Rom) out of his ass and just write concisely, which a guy that left a review a while back somehow doesn't seem to understand the issue with to my utter amazement.
And the Futa Conundrum has never really left. They don't get loads of new members but because of the way the game is, you'll naturally have to fend through the girls with dicks forest regardless because they were given too much way back and this game works like an apartment building that's being constantly given new floors with the changes and adaptations to whatever's happening. And they don't have elevators, you gotta take the stairs.
Funny thing is that I would love if some bigshot YouTuber did a video on this. Like, give me a Whang vid of him going through each phase of the game's development and the thread, it'd be glorious.
