I'd have to say that I often find the difficulty in Amiga games ridicilous.
Shadow of the Beast I & II comes to mind (the games are not challenging, they are ridicilous. Beast II is complete and utter crap, when not only having to die like 30 seconds into the game, made sometimes last 5 minutes, but ALWAYS having to do everything all over and watch that really looooong and boring game over sequence... Beast III doesn't even feel like it belongs in the series, considering its great gameplay qualities which Beast I & II so obviously lacks).
Super Stardust (I've played the game for ages and never ever even been close to beating the darn thing... and using them other weapons, well, sometimes it feels just to risky to enter the weapon & upgrades menu to even bother about it).
Rock'n'Roll (is it a joke, no level codes? how on earth is one to beat the game with its huge and many levels? made it to level 8 or 9 at most)
Dune II (oh, let me se, what to do at this level... yeah, right, die 3 minutes after I've begun playing it, not even having the slightest chance of building up some kind of defence before those darn flying things comes destroying my base).
Kid Chaos (the level in the second world, where one not only races against the time but also have to smash them purple spiky things is completely insane. I've not even managed to race through the level only bothering about the time, how on earth am I then supposed to do it when bothering about smashing them things?) and so on and so on.
The list could be made really long, but since I am getting really upset here I'd better not go on at this very moment.
