It's not so much about fulfilling wishes and stuff but more about what was promised beforehand and what was delivered. He said there would be some romance with Lisa and Max and then we get Vicky and the "I wanna watch you fuck other women" dead-end arc. Sure, wouldn't be too bad to introduce her along the lines, but it completely blocked everything and as of now it doesn't seem like it'll get a lot of progress at the moment either.
We all know that it's not what you say, but how you say it, but we also know that although he seems pretty upset that he's mostly right about it.
As for the romance part it's not the end of the world if you can't imagine that it could be present in an incest game (they didn't stop being regular human beings/men/women with emotions, did they?), but if you promise something like this you should get someone who can. I bet there are probably lots of people who'd even do it for free or a little honorable mention or something like this.
Tbh although you make some good points I think you've missed one of the key marks of the game. Max, as a character wants to have sex with his whole family. As a player the majority of people want him to have sex with his whole family - been so since the game first got real traction. I don't understand how romance EVER works in a harem relation especially when incest between previously proclaimed 'sex addicted' characters is involved. Let's be honest here, Kira and Alice do not believe in 1-1 relationships, been evident since the start. Anne - although committed to a 1-1 relationship legitimately had sex with Eric an unholy amount of times a day for a couple that was about to marry with kids in the house - I mean you have no idea what she does when she left to Eric's place. Lisa is a teenage girl who had anal sex with her brother, is the majority of her attitude really THAT unbelievable?
Although romance has played an underlying feature in near every relationship bar Kira's it was most definitely not prevalent. Even in Alice's relationship with Kate the major reason for Alice's loyalty was because Kate saved Alice's life. The whole 'I'm into watching you have sex with other people' is totally believable if you take into account everything we've seen to date including her whole submissive fetish.
Does this game have dead arcs? Sure. Do the updates fall short of what's promised each month? Sure. Is Lisa acting so completely out of character? Not if you take into account what I've listed above.
Although the complaint that Alice is overused is semi-valid it isn't really true. In terms of content you have: Blog sex, Anal Movie, Spider, Punishment and Kate.
Lisa: Anal kitchen, Training, and Alice's bed.
Although she's behind two she's not exactly underused like Anne who hasn't even had a sex scene to date. In terms of repeatable blowjobs etc. I'm pretty sure they're even - infact Lisa may be ahead considering twice in the shower and once doing her homework + at night with the handcuffs and a potential event again where she handcuffs you AND the whole punishment system adding another one to the mix.
Although it seemed totally wack the direction he took when I really thought about it after reading all these comments wasn't totally unexpected. Haven't slept in a day so I hope it was legible.
