Sure, the more otome games you play, the more chances are that you will keep encountering the same seiyuu over and over again. After completing more than 20 otome games I can instantly recognize such seiyuu as Sakurai Takahiro (my favourite), Kakihara Tetsuya, Taniyama Kishou, Miki Shin'ichirou, Hino Satoshi, Kaji Yuuki, Morikubo Shoutarou, Toriumi Kousuke, Hirakawa Daisuke and many others. Sometimes I don't recognize seiyuu right away, but after listening to him for a while I realize that some of his intonations are similar to a character I encountered in another game. Would I buy a game just because of my favourite seiyuu? If I wouldn't like a plot, then probably not. But if a game had a good plot AND my favourite seiyuu, then it could be an additional argument for buying this game.
