Actually, I'm guessing most of you have never heard of Gimmick!, let alone played it. Hell, I didn't know about this rare Famicom game until a few days ago, when I read about it over at tinycartridge.com.
This Sunsoft-published platformer was released in Japan in early 1992 and in Sweden in early 1993. As you'll see in the video below, Gimmick! (or, Mr. Gimmick, as it was known in Sweden) looks and sounds and plays like a mashup of Mega Man and Kirby's Adventure.
For more information on this cult classic, check out its Wikipedia page or this write-up over at GayGamer.net. Or, if you're not opposed to using emulators, track down a Gimmick! ROM and the latest version of FCEUX and give it a try. Just don't expect an easy ride--despite its cute and cuddly exterior, Gimmick! is hard as hell.
