Personally I always pronounced it like it's a French word. Some of their words are spelled similiarly, so I just went with that.
I really like this story!

All these chapters are just plain awesome so far, and I've wondered about all the same things as I played through the game myself. I almost never played card games at all pretty much exactly for the reasons that Vivi illustrated, and when I saw the name "Oeilvert", I couldn't help but give a mental "wth?" and wonder how in the world it was pronounced. Though I've always said it like Zidane, I like Vivi's suggestion the best. Mostly because it's just easy to say.

Great job parodying the game, it's very entertaining. I'll be looking forward to future dots to be disconnected.

I always pronounced it like Zidane did... I guess there is a debate about the subject, though. Quina's line is just so... like him/her. And of course Eiko thinks Zidane did something. And Steiner. *sighs* Anyway, thanks for updating! Here, you get a Zidane plushie! *pulls one out of her backpack* Don't worry, I have about 5 more.

These do make sense, and they make you laugh! Good job! I was expecting something really short, but no, you made this an actual story. Can't wait for more! And why does this not have reviews? *angry face*
