What games have the coolest spine art?

I don't know about the USA cart spines, but the Japanese ones really do look colourful and stand out on a bookshelf.

My favourites would have to be Real Bout Fatal Fury Special, Raguy, Mahjong Kyoretsuden, and Vlotage Fighter Gowcaizer (haven't got that game yet, but I will soon!).

Slug X jpn, for sure.
Gangan jpn is pretty cool too.

Metal Slug 2
Kabuki Klash
Mark of the Wolves
Stakes Winner 2
Syougi No Tatsujin

i like motw just for the yellow.
i m not sure why but i really like the scheme.
i also like the jp 96. instead of writing dull
jp text down the spine they put the faces there.
and funny thing. i actually like the us 96 spine too.
the whole sharp text on red is super.
