In Super Ghouls N Ghosts after you "beat" the game the first time you had to go back and defeat the boss again with a certain weapon. So technically to beat the game you had to play it twice while keeping that weapon in your possession. And the weapon sucked. Needless to say I only beat Super Ghouls N Ghosts once.
Ninja Gaiden I was hard, I beat that.
Mike Tysons Punch Out wasn't that hard at all. Although I hated the 2nd Don Flamenco because he would make you punch him so he could block it, and I hated turning pink.
Obligatory Mega Man reference.
Super Contra I beat and that was somewhat difficult.
F Zero on the Gamecube was somewhat difficult, beat that.
Legend of Zelda II. I remember having to call the Nintendo long distance number to get the correct sequence of spells to beat the last guy.
Chrono Trigger wasn't difficult, but I always got my ass kicked at the last guy. I played it soon after the PS1 came out so I really didn't have the patience to level up or purchase more megaelixirs.
I think Rush N Attack was probably difficult at one point, but I have beaten that game so many times its just like
ing Pavlov's Dogs playing that level. Only sometimes do the parachute shooters get me.
Timesplitters 1 on all difficulty levels was exceedingly difficult.
And definitely Battletoads, that god damned bike level. The whole thing that decided whether you were going to beat that game or not was that one level where you were sliding down that cave with the vines and would hit the birds back and forth to get 1ups. If you got 1ups you had a good chance of beating the game.
Shadowrun for the SNES was hard in that the directions for what you were going to do weren't ever outlined that well at all. So you'd spend half the game arbitrarily running around.
I think the hardest thing, was beating all the time challenges on Goldeneye, especially beating the Aztec level in like 11 minutes on 007 Agent, that was
ing insane. I still remember running to the launch pad with agents shooting klobbs at my back.
