The Karate Kid - nes. Biggest pile of shit i ever played.
Dammit! I was so close to actually getting to answer one I knew. I used to have that game. I played it a bit... looking back on it, I can't see why I didn't consider it to be absolute shit... only four levels, all consisting of pretty much the same thing with enemies who are exactly the same but have slightly more hit points... I guess it's because it was an early NES game and I was six, and back then no one really thought critically of video games.
Oh yeah, it is indeed Body Harvest. I wanted to post a screen of Rescue: Embassy Mission for NES, but couldn't find one.
Hmm... since it's been over three hours, why not...

My mom bought me this when I was like, seven. I still don't know why.
