Ninja Scroll (1993) is one of those rare anime that I really enjoyed. Yeah, I was a gaming/comic book geek who studied Japanese, but I never really got into anime. I'd watch them from time to time, but I didn't really go nuts over the format. I tended to view each movie or TV show as I did any movie or TV show, rather than just accepting it as good because it was Japanese and likely had tits.
A funny story is that my sister got me this film on VHS for a Christmas present, but it was the English dub. A buddy of mine who couldn't speak any Japanese besides 「どうもありがとう、ミスター‐ロボット」had the, annoying to him, subtitled version, also as a present. Why we never switched I don't know.
Anyway, Ninja Scroll is a pretty good movie. It's got a compelling story, interesting characters, and of course the ninja all have over the top powers. This makes it very D&D.
The only problem is that everyone and his sister, especially in the 3E days when I was heavily involved in the WotC Oriental Adventures message boards, wants these cool ninja powers as part of a ninja class.
No! The Devils of Kimon should be monsters with some ninja skills, folks. Those are racial powers. No D&D ninja class needs 'control bees from a beehive that grows on your back' as a reward for reaching level 6.
