Well as much as I LOVED Shugo Chara and Shugo Chara Doki, Shugo Chara party is turning out to be a fail in my opinion.
I still enjoy the actual story of Amu, her friends and the charas but all that game show stuff by the cosplay girls is a bit meh... They also fail in what I like to call the "short story time" and they keep calling Miki a boy (he, his) when it's a world wide fact that Miki is a girl, they've already covered this a long time ago and it seems they wish to change it.
I think they failed to think about their loyal audience (kids/teenagers from ages 10 to max 18), completely forgot about us and started trying to reach an audience of kids between the ages of 3 and 10.
This is just my opinion but good luck to them.
