Ever played a game that was so hard, and no matter how many times you tried you couldn't beat the game, or maybe even a certain mission/level?
The only one I could think off the top of my head was Red Dead Revolver. (Granted this was when I was a kid)... .I was playing the last mission and for the life of me, I could never beat it. No matter how many times, different tactics I used, I would always die.... And I would get so close, and bam, I die.
Maybe ill rebuy it and try again.
Now if we are talking about games you never beat cause it sucked or I hated it... that list is much longer.
