We don't move on from this game AND we like to say things overtly here because we actually like this game a lot, and/or believe it has eve more potential, AND so that Doc can see the feedback and hopefully do something about it. We love the game, but a subset of us followers/supporters/fans hate the story line (easy fix for Doc). If we don't speak up, Doc will never know and he may start losing fans and supporters alike, unnecessarily so.
I care a lot about how well the devs (I support) do. Doc is at the top of my support list, along with Seath Black and Westy. If the developers we support do well, they keep rolling out awesome porn games. If we keep blasting them with unconstructive and useless notions of "Why do i care..."'s like yours, bro, then they stop making the game(s). Everybody loses out on something then...
To Doc: Dude, something went very wrong with your last few updates. Please be so kind as to fix and re-release your latest update to 23S? We would all appreciate it. Even the haters. Question: Why has the MC stopped travelling and finding new sisters? The last update(s) seem to have deviated from this central plot line, also the house is full of people we don't know at the moment. What's up with that?
Having said the above, your game is still awesome (albeit kinda "Pulp Fictioned" on the scripts), dude!
