Take a look at that screen shot and tell me what's the first game that comes to mind. No need to even read the description (though that only reinforces my suspicion).

The Joystiq story was the first I'd heard of it so I was pretty shocked how similar it looks to Guardian Heroes. I'd hoped it was being developed by Treasure themselves but the little information out there says some of the old GH team were assembled for the project. Not sure whether that makes the near plagiarizing look of it ok or not.
