The series is quite legendary for it's atmosphere, SNK made sure that carried over to the commercials. And the actress playing Nakoruru in the ad is pretty cute too (I use her quite a bit, but still suck playing as her due to how hard it is to pull off some of her moves. She is quite tough to face in battle as well, sher tends to seemingly read your inputs and counters). Jubei was OK in the ad as well, but looked a bit young for the role as Jubei really isn't tnat young. I used to call him the Japanese Samurai John Wayne, because of Wayne in Rooster Cogburn with eyepatch. Also, the voice actor of Jubei narrates this ad, and is the narrator for the second Samurai Shodown, as well as the fourth game.
All in all though, early SNK fighters were hard as nails, and SS1-4 are definitely tough as nails (the early Fatal Fury games, and first 2 KoF's, along with the Art of Fighting games will make you pull your hair out in frustration).
