Best soundtrack? Persona 3 and Persona 4. Equal parts immensely catchy and emotionally devastating - a lot of the songs have really strong emotional associations for me, not all of them actually related to the games. I usually sing along to the battle themes. (This makes combat easier, it totally does, I swear.)
A game you think would be cool if it had voice acting? Most of the games I like have voice acting, so... hmm.
I think Pokemon would be pretty cool with voiced dialogue, since the more recent games have started to get more detailed in the plot department. And voiced Pokemon cries would be super cool, even if it would probably start some kind of irate fanboy riot.
What game do you never tell people you play? There's nothing I'm so ashamed of as to be capable of shutting up about it, I don't think! I'm not good at secrecy. ...I have downloaded H-games for their character creators, though. Which sounds a lot like "I read Playboy for the articles!" but it's true, I swear...!
But there's nothing I'm super into that I don't talk about.
