I just finished one of Ada's boss fights and QTE events where all of a sudden you go from combat to having to smash the joystick left and right, yes one of those! I failed about three times so being ready I resorted to the controller killing method of turning the pad sideways and smashing the stick left and right with my right hand, at which point the circular outline under the stick slightly cut my skin.
Wow I mean wow even track and field on the ps1 wasnt this torturous. I have been a event host and a tester on kinect for two years, i went from ZX spectrum to NES to SNES to ps1 to pc gaming to 360 and gamed all my life of my 29 years, I never encountered something as annoying as the QTE in this game. The gamer in me hates them and the tester logic wonders how the hell they thought this was a good idea and thought the difficulty of these was acceptable!
One reason I know is padding, they put them in knowing you will fail and when you fail you do it again, its called padding and its to make their average game a little longer.
Maybe because you are supposed to spin them, not rattle them back and forth?
Calmly spin both analog sticks in a circular motion.
That's how I normally do these things.
The problem with RE6 is that there are certain points in the game where you certainly have to apply a bit of manic speed as you rotate the stick - for example attempting to fry those zombies during Leon's Chapter 3 results in nothing unless you're winding fast enough.
What makes things worse is that, if you've played games for a very long time (for example the near-30 years I've been playing them) and for long sittings on average (like me, around 12 hours a day most of the time), you build up slight injuries and weaknesses in your fingers and hands.
From time to time I now get severe arthritic pain in my thumbs and fingers, so some of these rotation QTEs can occasionally hurt quite a lot, but I usually get through them even if I end up putting the game away for about two weeks and trying again when my hands have had chance to recover.
