this game is quite dead to me when there's no voice actors
Voice acting is fine if you've got a small cast and content that's rather simple - Snow Daze is a good example.
SS on the other hand has a huge and very diverse cast and a lot of characters, who totally depend on the right voice, dialect, delivery and comedic timing. It simply requires a higher level of professionalism and as such it almost certainly will never happen.
No idea how they could stop being curious as the entire arc was more about her mom than her, and the final sex scene is probably the worst one in the game, even back then. Being told to please wait for it to be updated caused me to more or less stop caring and just drop back in every couple of months to see if anything is new.
Curious compared to other characters, that is. We know what Mia is about, there's a sex scene with her, etc. - it's different compared to let's say Annie or Ronda, where there's "everything" to discover.
As far as I recall, DC's plan was to add a second update quickly, so Mia would be the first dateable girl. Sadly she's lost all her polls since and as such that never happened. Now she'll likely be the last schoolgirl to get finished, unless she beats Roxxy's pregnancy update.
