Hey, if Nobunaga's Ambitions included catching all the Pokemon, I can't see why Atelier Warriors would be such a stretch. A crowd of moeblobs tossing Barrels! at wave after wave of unsuspecting crowds of generic faceless cannon fodder until some animorphic tree beast makes makes for your Atelier base then you have to barrel your way back in an effort to intercept said tree beast and Barrel! it to death, isn't that hard to come up with.
