Top 10 Most Difficult Games Of All Time

Everyones list will be different. It will be in everyones experience what were your top 10 most difficult games. here is my list:

1.Ninja Gaiden (Nintendo)
2. Bayou Billy (Nintendo)
3. Robocop (Nintendo)
4. Battletoads (Nintendo)
5. Castlevania (Nintendo)
6. Ninja Gaiden 2 (Nintendo)
7. Ghouls & Ghosts (Arcade)
8. Teenage Mutant Ninja Turles (Nintendo)
9. Double Dragon (Arcade and Nintendo)
10. Shinobi (Arcade and Neo-Geo)

Now Bayou Billy could have taken top spot but i have spent at least 1 month at least to complete Ninja gaiden. most games take me a few days depending on how much time i have. unless its an RPG. i usually wanna take my time

Games that almost made the top 10:

Zelda 2
Contra (please keep in mind without the up,up , down,down,left,right,left,right select, start. you would only have 3 lives)
Devil May Cry
Devil May Cry 3
Shinobi (Playstation 2) extremely difficult but manageable.

Driv3r on PS2 - i liked driver, till they ruined its reputation with this...

I like smackdown on Playstation. it looks real game. i really very enjoy

Soul of Darkness - java game (only the moments when you changed into a fish, the most annoying thing otherwise the game is cool)
