Cobra Command on Sega CD has to be the top seed for me. I could always get to about 3/4 through the final level, but could never beat the game. This was back in the day when running out of lives meant starting the whole game over again. I don't remember ever feeling so frustrated.
I was a pretty young kid at the time, and I would get raging pissed and curse and scream at the TV. Then my mom would not let me play games for a few days. After those days were up, I try Cobra Command again, and the cycle would repeat.
