I have both games. I love them both, I like being able to read whats going on during the senarios and what not. But I like the song selection more from the original because well I get less distracted.
However, the movements for the squad way better in EBA than in Ouendan, they're a lot more smoother and actually do different actions (for the most part) for each song. Yeah I probably shouldn't be paying attention to them dancing, but you do notice it.
I'm stuck on the last stage for Hard in Ouedan, and I'm on Hard as well in EBA, but not quite at the end.
Both fun, if you don't want to spend the extra money to import the original then EBA is good enough. But I do reccommend looking into getting the original. Things that they cut out of EBA: the fire when you have a long combo, I kinda miss the fire when you're… on fire, and I just found it funny when they'd groan when you missed.
