Truthfully, I probably could publish five or even 10 posts about Super Famicom cover art, but I think two are plenty for now.
Anyway, as the header above states, here are five more of my favorite pieces of Super Famicom box art.
Gaia Gensouki--No joke: I'd actually like this particular piece of cover art more if the characters in the sky were removed and then replaced by the game's logo. That said, I'm pretty fond of it as is. This one was called Illusion of Gaia in North America and Illusion of Time in Australia and Europe, by the way. (Above scan was nabbed from the always fabulous gamengai.com, by the way.)
Rudra no Hihou--Talk about dramatic! I like every element of Rudra no Hihou's kaleidoscopic box art--especially the angrily orange backdrop (complete with a devilish pair of eyes). I also like the character designs, which aren't your typical JRPG fare.
Kiki Kaikai: Tukiyozoushi--This one's kind of a mess at first glance, but let things sink in a bit and you'll likely look at it as I do: as a near-masterpiece in the realm of Super Famicom box art. If only the protagonist's eyes were less freaky. Oh, well, it's still completely wonderful even with their presence.
Septentrion--The only Super Famicom game included in this post that I've yet to actually play in some form or fashion. I'm strongly considering it now, though, thanks to its striking cover art. I especially like the font the folks at developer (and publisher, in Japan) Human Entertainment used for its logo.
Super Mario World--If there's a piece of Super Famicom box art that can be called "iconic," it's the one seen above. (True story: I regularly attempted to recreate the central illustration using pencil and paper as a teen.) And what a brilliant idea to surround everything in bright orange and yellow, don't you think?
A few other contenders: Cotton 100%, Dark Half, Marvelous, Mother 2, Pop'n TwinBee, Romancing SaGa 3, Star Fox, Tales of Phantasia, Tenchi Sozouzou and Yoshi's Island
