Sometimes "insignificant" characters can be interesting, Odile-kun. Olrox from SoTN was an even more "insignificant" character, being just a boss, but people have had threads about him and his relationship to the plot, his reference to Nosferatu, etc. before. If Mr. Waffle wants to have a thread about Angela, that strikes me as no less legitimate. ~_~
That said, I wouldn't say "no one" has played this game, at least 'round these parts. Yes, the game hasn't been released in the US, and it's a pachislot game, but it still has its interesting elements--Angela is one, and the music is another. I wouldn't call her game one of the best ever entries in the CV series nor her one of the best characters, but it still seems fun to discuss her and the games.
