Gamertell has posted an opinion piece that points out the similarities between characters in two companies' games.
From the article:
"As I began playing Final Fantasy Crystal Chronicles My Life as a Darklord, I was faced with an overwhelming sense of deja-vu. Not from the gameplay. No, the way the tower defense title is executed is quite original and refreshing. It was the characters.
The bratty, teenage girl with delusions of grandeur and the cute, unassuming monster minions seemed familiar somehow. After I finished the tutorial, it hit me. Mira and her tonberry servants seemed eerily similar to Etna and her prinny servants, from NIS' Disgaea and Prinny: Can I Really Be the Hero? games."
