In the end, Destructoid would say that Arcana Heart is not recommended for the type of gamer it seemed to be marketed to. They think they'd become frusturated no matter how cute the girls are. Arcana Heart is like a wolf in a very moe sheep's clothing.
It may look like a silly anime girl brawler, but the underlying complex fighting system can provide a challenge to even the most seasoned fighting game fan. If you've got the fighting game chops, overlook the underaged girls and give this one a chance.
