10. Dr. Jekyll and Mr. Hyde

Here is a game that is more complicated than possibly any other game I've ever played. You start out playing as Jekyll, and the townspeople are trying to stop you from getting married. So you walk very slowly across the screen until you get hit enough that you turn into Hyde. You can also poke people with your cane as Jekyll, but I found this to be utterly useless. Once you turn into Hyde the day turns to night and the screen starts to scroll from right to left instead of left to right. I think the bastard developers did this for the sole reason of confusing you, because they knew that if anyone ever figured the game out they might have fun playing it, which is downright crazy. Now that you're Hyde, the screen goes auto scroll and enemies come at you endlessly. Eventually you die, and the happiness starts to kick in. All in all, I think the townspeople should have saved us some trouble and just cut Jekyll's head off so he couldn't turn into to Hyde period.
