I don't know how many people have played Arcana Heart (the following is a bit niche, to say the least), but Atlus is keeping the 2d fighting genre kicking here in the US by bringing the title to these shores in April. Gamasutra has the news:

"Publisher Atlus has announced it will be continue to support the still-strong PlayStation 2 by bringing 2D all-girl fighter Arcana Heart to the North America this April.

Sporting four different modes including arcade, story, versus, and training, as well as an unlockable extras gallery, the game centers around elemental spirits from called Arcana which particular humans can call upon.

Atlus says the game, when it launches in April, will feature 11 female fighters with customizable attack and defense skills, as well as "11 different Arcana to pair with your fighter." It also notes that the game features "huge battle maps" for vertical fighting with "air dashes and homing techniques to create devastating aerial combos."

Though some will inevitably be turned off by the all-female cast, AH provides a lot of depth if that's your kinda thing in a fighting game. As for myself, I've had the chance to play AH, and while I don't think it's fantastic, that may be because I've been told the character I want to play is about the hardest execution-wise in the game. The game itself also seems to play a bit slower than Guilty Gear and even old Super Turbo, which I'm not a fan of. However, if the game is priced affordably when it comes stateside (under $50) I'll probably pick this one up.

For those who've never seen the game in action, check these youtube videos (they're from SBO, the biggest tournament in Japan):
