Producer also uses a male pronoun and talks like a guy. It's pretty obvious the producer is meant to be a guy but that doesn't mean girls can't play it.
And I'm not saying they can't - quite a bit of the forum's proof - just stating my observation. As it is, they seem to be trying to strike a balance now.
Maybe the anime adaptation ISN'T that great in terms of staying true, but then, considering the fact the main game is essentially structured by routes, they could either focus it on a particular idol (which would push away other idols' fans. I know Chihaya/Haruka got larger focus than others, but I believe the idea's understood - I think a lot of people would be miffed to see someone take all that money and effort and put it only on one) or take the method they did. (Or separate routes-by-episode, but with only 25 episodes, that would make for really bad and/or rushed pacing)
I think it's difficult to introduce people to the series by game-first, because of the fact it's near-purely import-based (unless your attempted convert owns an iPad, and I don't think Shiny Festa makes a good gateway). The only person who I know is an import gamer does not own a PS3 (and while I never asked, I doubt has a Japanese Xbox/360).
