Games that make you scream,"Omg this is too hard!"

[Soma]

Battletoads is the most difficult action game I've ever played.

I could never finished Perfect Dark on Perfect Agent difficulty. I got to Carrington Institute Defense, where you have to save hostages, but didn't knew what to do after you saved them.

Fighting game? Castlevania Judgment is not too difficult, except for Dracula and the Time Reaper, which is extremely difficult on Hard Mode, I don't want to know how difficult will be on Brutal =S
