Does zero chance count as a factor? I was playing Castlevania: Lords of Shadow and not particularly enjoying myself the whole 2 hours or so it took to reach the first collosus big, big boss monster.
"Oh, great," I thought, "because Shadow of the Collosus's frustrating-monster-climby bullshit did so much to hook me I quit on the third one." Gabriel at least didn't have to worry about a grip guage, but after I broke the first rune, the fight was over. All I could do was stand on the golem's arm pushing every button in vain next to his big, glowing hand until he drew it back to swat at me again, whether or not it hit me apparently being decided by invisible dice.
At this point I stopped caring about Captain Picard's tale of man-stalking and joined those that think Castlevania should stop taking 3D before performances. Shanoa's murderously-overpowered-boss adventure was much more fun than this.
