My list...
This game called POW for the NES. It was some action game that I got for X-mas. That thing was hard as the devil. For example, in the 2nd level, you have to kick and punch this guy that kept shooting a gun that can kill you in one hit. And since you don't pick up many lives in the game, that is about as far as your get unless you happen to have the skill of god.
Lion King for SNES. I loved the movie, but not the game! Terrible controls, and for a Disney game, it sure was anything but a slice of cake. I couldn't count how many times I died trying to master those jumps on the "I cant wait to be King" level. And even then, the you have a pitiful amount of lives to began with.
Lord of the Ring for SNES. This would make Tolkien roll over in his grave - again (I'm sure he did on the animated movie). The caves that you had to explore were huge labyrinths that have little or no change to each "section". Its more tedious that you had to explore every nook and cranny of these caves to collect a bunch of scrolls and amulets that has NOTHING to do with the books. Did I mention that the CPU's of the other characters are amazingly stupid?
Yoshi's Story for N64. Took me 20 minutes to beat and the levels were super easy and virtually the same [darn] thing over and over again: eating fruit.
Mario is Missing for SNES. An educational game. I play to be entertained, not to learn.
Final Fantasy II for NES and PS1. The way you gain strength and level up is... ugh. That's too realistic if you ask me. Does beating yourself up to gain HP and having skills actually going down sound appealing?
Now if you want to know what are some of the most worst games of all time are...
