oh i have a few
for example, i never managed to finish Donkey Kong 64 back in the day because of that stupid arcade game you had to go through twice in order to get a Rare Coin

Last winter i bought a N64 again, with DK64, and some other titles we played. maybe ill try to beat it soon

too many great memories.
yep the Driv3r mission in istanbul was a pain aswell. but i got it right after a few tries.
the Zero missions in GTA SA were pretty annoying to say at least. i just started a new game. somehow i managed to do finish the "follow the train with smoke shooting" mission right on the first try, even before he reached the country side were you need to take the higher dirt road ! just stay on the right side of the other track as far up front as possible and he pops them pretty fast.
oh and pretty hard aswell, trying to beat Operation Flashpoint Dragon Rising on Hardcore. No Checkpoints, No HUD, No respawns even for your companions. and missions that can take up more then an hour...with the fact that every single bullet can kill you instantly! in one mission were an attack helicopter is nearby and will shoot rockets at youre squad when he spots you, he killed my whole squad with just 2 shots. i barely managed to escape, run like hell chased by alot of enemy's and got flanked in a field without any cover. i somehow managed to take them down one by one in a the field and could complete the mission on my own, without sprinting ability's because the legs aswell as the arms had major injury's. damn what a relief!
the mission with the Monastery up a hill was annoying aswell. when you finally reach the hill you get mortar fire so you cant take it easy.
when you reach the hill the mission is timed and there are ALOT of enemy's up there. first time around i was out of time and had to start the mission ALL over again, second time i got killed, restart....third time my team gets killed but i managed to kill everyone except the very last enemy alive...he puts a bullet straight trough the head so it was instant death for me #$%^&^*# restart...after about 6 tries i finally got them all
did manage to finish the game though, and got the platinum trophy
oh and of course, trying to gold the vettel challenge
