Factory sealed Killer Instinct for Game Boy

[Scrimble]

I came across one today but I passed on it because I think it was priced too high at $30. I am unfamiliar with GB prices so I was wondering if it was a good deal or not. Any help is appreciated.

Yup. Probably worth at least $50, esp. if you use those recent auction lots as a guide.

Factory sealed GameBoy and Gameboy Color games don't go for a whole lot, even the good ones.

I've had Megamans and Marios that sold for only $25-$30

I would have passed too...

I don't think sealed on that game matters so much, it's unplayable either way ^_-
