You know, the whole pirates vs ninja thing was my whole reason for getting into One Piece in the first place. It was a way of expressing my anti-Naruto sentiment.
Having watched both I really like One Piece a lot more. Especially since it progresses so much faster and doesn't feel like any other anime out there. Plus its a lot funnier, I'm a fan of comedy more than anything if you couldn't tell.
I would totally import a One Piece vs Naruto game.
I went out of my way to download Arm Joe after all.
